Fourier Transform and Sampling

This lecture covers the Fourier transform of a signal sampled by pulse sampling, reconstruction of the signal in the frequency domain, harmonic response, and the interpretation of the transformed signal. It also discusses the relationship between discrete sequences in time and frequency, the reconstruction of signals from their Fourier transforms, and the properties of the discrete Fourier transform. The lecture emphasizes the importance of sampling in both time and frequency domains, the interpretation of sampled signals, and the reconstruction process using the Fourier transform.
