Description

This trainer has been designed with a view to provide practical and experimental knowledge of Pulse Code Modulation/Demodulation.

Specification :

1. Power supply requirement : 230V AC, 50 Hz.

2. On Board Modulating sine wave generator

Frequency Range : 300Hz to3.4 KHz.

Amplitude : 0 to 5 Vpp.

3. On Board Sampling Pulse signal generator.

Frequency Range : Fast Mode: 1.2MHz, Slow Mode: 1Hz

4. Built in variable DC power supply (0 to+ 5V) to see the effect of DC on the output waveform.

5. LED indicators for PCM output bits.

6. PCM Bit : 3 or 4 bit selectable by switch.

7. Modulator Sections : Counter & Comparator, Encoder

8. Demodulator Sections : Decoder and Low Pass Filter.

9. All parts are soldered on single PCB with complete circuit diagram screen-printed in multicolour.

10. Standard Accessories : 1. A Training Manual

2. Connecting Patch cords.
