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
