R = 4800 x 3.32 log (4) = 4800 x 2 = 9600 bits/s If there’s only one bit per symbol, as is the case with binary NRZ, the bit and baud rates remain the same. Multilevel Modulation Techniques ...
AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well.
This hardware is just an Altera MAX10 board, with a single input used for serial data of the audio to be transmitted, and two outputs, each connected to a few bits of wire for a quarter-wave antenna.
