objective: observe change in position of clock pulses according to the amplitude of the modulating signal at the different clock frequencies.

* recovery of modulating signal from demodulators circuit.

Specifications: . in built DC regulated power supply  12v,+ 5v/ 300mA

* on board modulating signal generator.Frequency : Fixed Amplitude :  0-5 Vpp Approx.

• On board sampling pulse generator

Frequency : 8KHz, 16KHz, 32KHz,64KHz Amplitude : 5 VPP Approx.

• Modulation using IC 7555 Multivibrator

• Demodulation of PPM using 4th order /low pass filter & AC amplifier using TL 074

• Glass Epoxy PCB used as front panel
