Lecture
This lecture covers the properties of Discrete-Time Fourier Transform (DTFT), including DTFT pairs, constant Kronecker delta, harmonics, step function, one-sided exponential, arithmetic-geometric sequence, sinc sequence, and box sequence. It also discusses linearity, shift in time, shift in frequency, time reversal, differentiation in frequency, convolution in time, circular convolution in frequency, conjugate symmetry, and Parseval's relation for aperiodic signals.
