Hi guys,
I have a question with regards to a Digital reciever, which unfortunetly,I cannot post any info on (to avoid getting into trouble). It basically accepts a digital waveform and toggles the input data according.
I basically have one question. This reciever has two thresholds, Vhigh(ac) and vhigh(dc) ( and the same for the vlow), which are used to prevent the "ringing" of the input wave from the toggling the input data.
Is it common practice to have 2 different thresholds for toggling ? Like, I understand that the input waveform may have some noise, and that we wouldn't want the circuit to switch if the noise crosses our toggling threshold. So wouldn't we just have 1 threshold, and make it high enough ( or low enough ) such that the noise wouldn't cause it to switch ?
Thanks guys, I know i don't have much info .. unfortunelty I can't talk much :S so I appreciate anything you guys give me..
