The amplitude modulation and demodulation trainer consists of an audio signal generator, a carrier generator with facility for AM modulation. The demodulator section consists of a diode demodulator and low pass filter to extract the modulating signal. Provision is made for the students to observe the waveforms, at various stages and also has facili

Pulse code modulation and demodulation is one of the techniques used in digital communication. In PCM the analog signal is sampled, quantized and converted into binary code . These different processes constitute what is known as PCM. The kit consists of an analog signal generator, clock signal generator, an analog to digital converter, digital to a
