Transition to/from Continuous Time Signals and Passband Modulation

This lecture covers the transition between continuous time signals and passband modulation, discussing topics such as linear and nonlinear modulation techniques, lowpass vs. bandpass transmission, linear baseband modulation, Nyquist sampling, and the complexities of baseband signals and transmission. It also delves into the concepts of passband modulation, complex baseband representation of passband signals, and linear passband modulation. The instructor explains the direct conversion of analog bandlimited signals, the architecture of passband modulation of analog signals, and the all-digital RF transmitter approach for passband communication.
