Power Point presentations for Digital Communication

All slides for Digital Communication will be uploaded in this post.

1. Presentation on Nyquist criterion, Aliasing, Reconstruction
We have discussed Nyquist criterion (impulse sampling) and aliasing effect in class. But, reconstruction of signal has not been discussed due to lack of time. Study it on your own. I shall try to discuss the topic before final exam if we get enough time.

2. Presentation on PCM and PM
Pulse Coded Modulation (PCM) and Pulse Modulation (PM) are both important topics for your exam. There are extra graphs and figures included in the file for your better understanding (they will not come in exam), follow class note for probable exam questions.
