Objectives of this experiment:
1. To construct a pulse amplitude modulation generator and to observe the characteristics of both single and dual-polarity pulse amplitude modulation.
2. To construct a PAM generator, using an IC – timer as a sampling clock.
3. To observe how its output can control a C-MOS sampling switch.
4. To identify that this output wave is a dual-polarity PAM and To adjust the depth and frequency of modulation.
5. To obtain a single-polarity PAM from this circuit, by adding a DC reference level to the input sine wave.
6. To observe that the output waveform is a Single Polarity PAM.
7. To observe the demodulated waveform using detector.
Built in regulated power supply: +9V/300mA.
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
