Pulse Amplitude Modulation and Demodulation .
We are a renowned name, which is engaged in offering an unmatched range of Pulse Amplitude Modulation and Demodulation (PAM).
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
