Frequency domain representation in discrete time signal and system

In digital signal processing, frequency domain representation of discrete time signals and systems is a fundamental concept. In this video, we initially define the eigenfunction and eigenvalues , define the frequency response or the transfer function of an LTI system, solve example of perfect delay system and find its discrete time Fourier transform (DTFT), point towards the inverse Fourier transform and also link the 2 pi periodicity of frequency response in DTFT. The content of this video is primarily based on the following references. 1. Discrete-Time Signal Processing by Alan V. Oppenheim, Ronald W. Schafer, with John R.
