Analog Signal Sampling and Reconstruction .
Experimental Training Board has been designed specifically to study of Sampling Theorem using Analog Signal Sampling and Reconstruction
(Pulse Amplitude Modulation and Demodulation). The training board is
complete in all respect except C.R.O. Practical experience on this set
up carries great educative value for Science and Engineering Students.
Object:
- To study Sampling Theorem using Pulse Amplitude Modulation and Demodulation
- To generate PAM signal by modulating with audio signal by natural sampling
- To generate PAM signal by modulating with audio signal by Flat-Top sampling
- To generate PAM signal by modulating with audio signal by Sample / Hold circuit
- To demodulate using Low Pass Filter to reconstruct input(sine wave)
