Passthrough
In signal processing, a passthrough is a logic gate that enables a signal to "pass through" unaltered, sometimes with little alteration. Sometimes the concept of a "passthrough" can also involve daisy chain logic.
Examples of passthroughs
- Analog passthrough (for digital TV)
- Sega 32X (passthrough for Sega Genesis video games)
- VCRs, DVD recorders, etc. act as a "pass-through" for composite video and S-video, though sometimes they act as an RF modulator for use on Channel 3.
- Tape monitor features allow an AV receiver (sometime the recording device itself) to act as a "pass-through" for audio.
gollark: Oh yes, just calculate SHA256 hashes on paper.
gollark: Hardly. You can probably make it fairly impractical by banning exchanging it for fiat currency and stuff.
gollark: Just stop considering orbital death rays a problem.Anyway, apparently the "federal reserve" is likely to increase interest rates some amount next year. Someone elsewhere said that that would probably be bad for the stock market. Is that accurate?
gollark: Yes, people are weird and want it for social status/scarcity/whatever rather than because it actually looks nice "inherently".
gollark: (also, I'm pretty sure IPFS doesn't guarantee that your file exists forever at no cost, someone has to be pinning it or viewing it)
