Actually, that's called Frequency Division Multiplexing.Cable TV does not multiplex the channels. Each channel has its own band of frequencies.
You are correct, I was wrong.Actually, that's called Frequency Division Multiplexing.
Yes, when I hear the word multiplexing I also think of time-division multiplexing, since that's what's commonly used in sensor signal conditioning and processing, where I've done most of my work.Then an orchestra multiplexes its instruments? It doesn't. Many instruments use the same frequency as other instruments.
But I think multiplexing is time-division where channels have their own time slot and one channel pulses over and over with all the other channels pulsing in their own time slots during the pause.
