Bandpass Sampling

This lecture explains the concept of bandpass sampling, which is used for signals with a limited frequency range. The instructor discusses how to sample bandpass signals effectively, avoiding aliasing issues, and ensuring the preservation of information. Through practical examples, the lecture illustrates the conditions required for successful bandpass sampling, including the baseband condition and the necessary sampling frequency. By following these guidelines, one can obtain an alias-free discrete-time version of the passband signal, facilitating both sampling and demodulation to baseband in one step.
