The document contains 38 figures that describe various digital modulation techniques used in communication systems, including PAM, PCM, ASK, FSK, PSK, QAM. It explains how analog signals are converted to digital signals using techniques like quantization and encoding. It also illustrates key concepts like Nyquist theorem, signal constellations, and the relationships between bit rate, baud rate, and bandwidth for different modulation methods.
