Sampling and Reconstruction Trainer

Sampling and Reconstruction Trainer. The unit is one of a range of digital communication trainers and provides all necessary inputs and connections for students to study signal sampling and reconstruction techniques.

Experiments:

• Sampling and reconstruction of signal.
• The effect of II order and IV order low pass filter on reconstructed signal.
• The effect of sample amplifier and sample and hold amplifier on reconstructed signal.
• The Nyquist criteria for sampling and reconstruction of signal.
• The effect of sample /hold circuit on reconstructed signal
• Effect of sampling pulse duty cycle on the reconstructed signal in sample and sample hold output.
• Comparison responses of 2nd order and 4th order LPFs.
• Verification sampling and reconstruction data transmission scheme for
