1. Frequency Response After this lesson, you will be able to: 1.Know how complex exponentials are eigenfunctions of LSI. And show how this property leads to the notion of a frequency response representation of LSI systems 2.Know what are the Discrete-Time Fourier Transform (DTFT) and the properties of DTFT. 3.Explore how the discrete-time Fourier transform may be used to solve LCCDEs and perform convolution
