1 amplitude modulation modulation is the process of varying a higher frequency carrier wave to transmit information though it is theoretically possible to transmit baseband signals (or information) without modulating it, it is far more efficient to send data by modulating it onto a higher frequency carrier wave. One goal of this lab is to introduce python as a high-level tool for signal processing and, in particular, for the generation and reception of communication signals another goal is to be able to transmit and receive ascii text strings in python using at-top pam (pulse amplitude modulation) which is a simple baseband signaling technique.
