Pulse Code Modulation & Demodulation

SPECIFICATIONS: 

Output voltages (Regulated) : ±12V DC, +5V DC (Inbuilt) : 0-5VDC (as modulating signal)

Clock signal generator:  7.8 KHz & 125KHz/5VP-P  Approx

The PCM system is divided in five blocks i.e Clock generator, sample & hold Amplifier, A/D convertor, multiplexer, timing and control logic. Housed in ABS cabinet, circuit/ block diagram printed, connections of various components (IC LF 398, IC 0800, IC 74150, IC 74160 & IC 741), all important outputs & test points brought at Glass epoxy (PCB) front panel.

Also provided with power chord, patch chords & instruction manual.

Observe the conversion of DC signal into digital signal using sample& hold and A/D convertor.

Optional : Digital Multimeter

REQUIREMENT OF DSO FOR COMMUNICATION TRAINING MODULES
