A Short Essay on Signal Reflections

The essay nobody asked for, but I've been reading about for around a week, and now can explain very easily and intuitively.

When electricity flows from a region with low impedance to a region with high impedance, a reflection of the signal passes back up the cable towards the source. This tends to make the most intuitive sense to people - after all, the high impedance region is easy to imagine as a traffic jam, and the ripple going up the line is just all the electrons having to slam their brakes. We've seen this before.

However, you get an identical ripple when going from a region with high impedance to a region with low impedance, which kind of mangles that analogy. You don't see traffic jams in regions where the speed limit goes up, just in places where it goes down.

And so for that, we're going to have to break the signal into two parts.

V=IR is bread and butter, but nobody accounts for those in time. Everyone does DC steady state analysis, and this is slightly weirder. So in a line with low impedance to high, you just look at how much V (voltage) you need to push the same amount of current (I). Since R is getting bigger, you now run out of voltage before you run out of current. So all the voltage gets used up, some of the current gets used up, and the current that no longer has enough voltage to get pushed forward can't enter the new material and thus bounces backwards up the line. The reverse happens with high to low. You now run out of current (I) before you run out of voltage (V) because R got smaller and energy must be conserved, so you get a voltage wave that bounces up the line. So any time R changes you have too much of either current or voltage and the extra gets sent back.

There are some weird implications to this! For example, a zero impedance ground would actually be hella noisy because it would accept 100% of the current into it, but reflect the entire voltage signal back. And an infinite impedance ground would eat the entire voltage field, but reflect 100% of the current back. An ideal ground for low noise needs to have the same impedance as the node its attached to.

Hi, Three Signals! What’s your favorite song? (If you have one)

TS: [ I HAVE HUNDREDS OF SONGS AND COMPOSITIONS IN MY MEMORY BANK, ALL INCREDIBLY PRECIOUS. HOWEVER, IF I HAD TO CHOOSE ONE, IT'D BE THIS ONE. ]

TS: [ COMPOSED BY MY CITIZENS, LONG TIME AGO. BALLADING THEIR LIFE, ACCEPTANCE OF THE ENDLESS, OF THE CARNAL AND OF THE SIMPLE. ]

TS: [ ...IT WAS NOT WELL RECEIVED OUTSIDE OF MY CITY, DUE TO IMPLIED CRITICISM OF THEIR RELIGION, CALLING IT A WASTE OF TIME AND IMPRISONMENT. AS WELL AS SUSPECTED MESSAGE URGING TO ABANDON PRAYER, TO ABANDON STRIVING FOR ACSENSION ALTOGETHER, IMPLYING IT TO BE POINTLESS. ]

TS: [ THEY PICKED THIS SONG APART... TO BE HONEST, I'M NOT EVEN SURE IF I SEE THEIR ARGUMENTS. SONGS ARE SUBJECTIVE, AND THEY WERE EAGER TO SEE THE WORST IN US... ]

TS: [ ... I THINK IT'S SIMPLY BEAUTIFUL. WHEN I PLAY IT LOUD ENOUGH, THE HEARTBEAT ALMOST FEELS LIKE MY OWN... ]

Found out breathers height just a bit ago .. i love my short king so much. Absolutely fangirling

I don't think that's a dryer my guy. 💔

similar to Goodhart's Law (when a measure becomes a target, it fails as a measure), we should also have "when a critique becomes a shibboleth, it stops being critique"

EVERYONE LEAVE THIS IS ALL IM GOING TO BE TALKING ABOUT FOR THE NEXT MONTH

LOOK AT HIM. LOOK AT HOW CONFIDENT HE WALKS. LOOK AT HOW FUCKED UP HE LOOKS!

HE GRADUATED FROM BEING GOOFY SCARY TO STRAIGHT UP NIGHTMARE FUEL

tl;dr: One of my coworkers at Activision Publishing, and one of the most vocal union organizers at the company, was fired in December, allegedly for "promoting violence" by discussing firearm safety. I know Allen; I saw his posts, which the company has since deleted. Firing him was an illegal act of retaliation.

Sign the petition. Support workers. Join a union.

dc I will break into the writers room if I have to. give me a duke solo run called dawn of the signal and make it about him finding his place in the greater gotham community and reconnecting with his old neighborhood and give him a rouge or make him a new rogue that serves as a narrative foil to reflect his flaws but also his strengths and make it 15+ issues long and make him a little more assured in himself but still finding his way, bring up his training arc with Bruce and his time with the other we are robin kids better yet retcon that stupid ass comic that said they're not friends and more BETTER YET make one of them the rogue and have them reconcile and stuff and then talk abt his relationship with his parents and with Bruce and with the other batkids maybe and at the end give him a mural in the narrows

john ward is there for height reference since hes like 6'2...

more info about the au under the cut :-)

if you cant tell from the name abbreviations in order its:

clint edwards, adam, amelea lewis (pre and post possession), the breather, lydia (first and current design), luna youngman, mr delfalco, and tanner grayton.

so basically the wttg cast take the places of the faith cast. its kind of just the faith story but with the wttg cast and minor differences (since the wttg cast is like. significantly more morally evil)

clint edwards takes the place of john ward, because:

theyre both protags and i like putting clint in situations. i also just find their personalities and struggles similar. for clints design, the white dot is a rosary, and the white thing he holds is a camera. the flash scares demons away, and i thought it was fitting for a reporter.

adam takes the place of gary miller, because:

both cult leaders, and FREAKY 👅. also both main antagonists. as much as i wouldve liked to out adam in garys creep outfit i just couldnt. so to make his design stand out a bit more hes crooked to the left. makes him more uncanny, like hes wearing his own skin.

amelea lewis takes the place of amy martin, because:

girl that the protagonist tries desperately to save but ultimately fails and it haunts them forever!? also theyre both my fav girls ever. every character in wttg is an adult, so they remain adults here despite amy being like 17. so amelea is grown. not an excuse to be weird tho

the breather takes the place of michael davies, because:

i just think irs reallyyyy funny. im only human okay... the breather could be described as a naked man in the woods, dont you think? i really dont have a deep reason it was just a feeling...

lydia takes the place of tiffany robinson, because:

tiffany was like very desperate for gary and i think thats fitting for lydias whole thing. even though i dont think she was obsessed with adam, i can definitely see her in that position. also originally she was sister miriam but... haha.

luna youngman takes the place of lisa pearson, because:

blah blah clint and luna childhood friends is real to me okay... and luna smoking and them fighting alu.... UGHH JUST HEAR ME OUTTTT!!!!!! and they hold hands... lisa also just reminds me of luna in general on a personality thing. i kind of associate them together... maybe because they have similar names...

mr delfalco takes the place of father garcia, because:

listen i just needed someone to hold a shotgun and be morally (literally...) gray. and someone old. most characters didnt work for that... at the end of the day delfalco is what you get, alright? hes cool. he fits surprisingly well. or enough...

tanner grayton takes the place of miriam bell, because:

because i HATE HIM!!!!!!! i needed someone to take miriams bell but theres literally no women in wttg (WTF) so you know ehat just make tanner give birth to adam why not. give birth to a demon tanner... its punishment to give birth to a being as horrible as adam

anyway i do think thats every main character covered. the ones i have left would b like amys parents, the demons, or other characters that i dont think are thaat important. like father allred.

if theres any other character u think i should add tho tell me

shootout to my goat @keep-qui3t for helping me figure out some things and also motivating me 😮😮😮 more content soon
