The extra I look into it, the extra questions I get (missing any background in electrical engineering sadly).

It appears to me like the most well-liked and exhaustive articles on-line and movies on YouTube, one thing like this one by Andreas Spiess depart sure points out focusing fairly on “tips on how to construct a tool X” or “tips on how to write this code utilizing library Y” and not likely on “the way it works”.

Likely these are “frequent information in communication” assumed to be clear, however they don’t seem to be. Are there any sources (articles, movies) made for the “common viewers” which might assist me to know this subject higher?

My present questions are:

In keeping with this video we get “ones” and “zeros” encoded as completely different “on” occasions adopted by “off” occasions however we solely use two completely different obligation cycles (e.g. 0% and 50%): so it makes use of Pulse Distance Encoding. Will it nonetheless be known as pulse width modulation on this case?

Why “IR on” means “house” and “IR off” means “mark” in NEC protocol? I imply there may be most likely a purpose to do it this manner and never the opposite approach spherical?

Error correction utilizing the logical inverse of the code (additionally within the NEC protocol) as an alternative of the sending the identical code twice means we examine if our sender did not simply “caught” with sending zeros (or ones) and is definitely capable of ship each, proper?
