Pulse Amplitude Modulation and Demodulation

Pulse Amplitude Modulation and Demodulation The offered range is ideally utilized for studying pulse amplitude modulation and demodulation. Along with this, the offered range is available in number of customized designs, shapes and sizes in accordance with the diverse demands of clients. Object:- To demonstrate sampling of a sine wave audio signal thereby converting it into pulse amplitude modulated signal (PAM) To demonstrate demodulation of PAM signal thereby recovering the sine wave audio signal To demonstrate the effect of sampling-rate on the distortion in recovered sine wave audio signal The board consists of the following built-in parts:- ± 9V D.C. at 100 mA, IC regulated power supply Carrier generator circuit which generates the carrier signal Audio frequency modulating signal Variable D.C. is provided to see the frequency deviation in carrier frequency Frequency modulation circuit with buffer stage at the output Demodulating circuit Adequate no. of other electronic components Mains ON/OFF switch, fuse and jewel light The unit is operative on 230V ±10% at 50Hz A.C. mains Adequate no. of patch cords stackable from rear both ends 4 mm spring loaded plug length ½ meter Good quality, reliable terminal/sockets are provided at appropriate places on panel for connections & observation of waveforms Strongly supported by detailed operating instructions, giving details of object, theory, design procedures, report suggestions and book references Other apparatus required: Cathode ray oscilloscope 20 MHz
