This document contains figures and diagrams related to digital signal encoding techniques. It discusses analog to digital conversion including PAM, PCM, and the Nyquist theorem. It also covers digital modulation schemes like ASK, FSK, PSK, QAM showing their constellations and characteristics. Finally, it distinguishes bit rate from baud rate in digital communication.
