Module 3 : Sampling & Reconstruction
Lecture 26 : Ideal low pass filter
 
   Objectives:
 Scope of this Lecture:

We saw that the ideal low pass filter can be used to reconstruct the original Continuous time signal from its samples. However, due to  non-availability of an ideal low pass filter and problems associated with it, we look at an alternative method of reconstruction using a Zero-Order-Hold filter.
How to tackle the problem of low pass filter not being ideal .
To know about Zero Order sampling .
To study Response of the Hold Filter .
To study the types of distortions in the Hold Filter.
Reconstruction of Signal in zero order Hold Filter.
