What is the block diagram of PULSE AMPLITUDE MODULATION (PAM) and PULSE POSITION MODULATION (PPM)??? I just want to know the basic block diagram regarding of the two modulation given…. I try many times to see this block diagram on the internet but I am confused of what I saw because there’s no specific basic block diagram there…. Hope you will help me regarding my problem what is really the block diagram of PPM and PAM…
