The unit is one of a range of digital communication trainers and provides all necessary inputs and connections for students signal sampling and reconstruction techniques.
Features:
- Functional blocks indicated via on board mimics
- Test points
- Fully documented student workbook
- Crystal controlled pulse generator
- Demonstrates sampling and reconstruction as per Nyquist criterion
- On-board analogue generator (synchronised)
- 5 Selectable sampling frequencies
- Sampling Pulse Duty Cycle selectable
- Separate sample and sample/hold outputs
- On-board 2nd order and 4th order low pass filters.
Experiments:
- Study of signal sampling and reconstruction technique
- Study of aliasing and effect on reconstruction of signal due to various sampling frequencies
- Study of effect on amplitude of reconstruction signal by varying sampling pulse duty cycle in sample and sample/hold output
- Comparison of 2nd and 4th order Butterworth filters
- Signal sampling and reconstruction using external sampling input
