OBJECTIVE:
- The purpose of this MAX trainer is to provide the basic knowledge of the Phase Shift Keying (PSK).
- PSK describes the modulation technique that alters the phase of the carrier. Mathematically:
In this trainer we have used 1496 IC as PSK Modulator.
PSK Demodulator consists of 565 Phase locked loop IC and an operational amplifier to demodulate the PSK signal by adjusting the PLL to the centre of the PSK signal. To prove this fact by comparing the steady State input and output levels (i.e) the PLL output followed the Input level exactly.
Our PSK trainer consists of the following
Features:
Data Input, Carrier generator, Phase shift keying Modulator & PSK Demodulator.
1. Date Input:
Debouncing pulser is provided to give the Input instantaneously.
2. Clock Generator:
It is provided for Data Input of the PSK Modulator. The generated square wave frequency varies from 1Hz to 500Hz.
3. Carrier Generator:
This generator is provided for carrier Input of the PSK Modulator. It generates sine wave. Its frequency varies from 1KHz to 100KHz.
Frequency selector: X1 - 1KHz to 10KHz (approximately) X10 - 5KHz to 100KHz
Amplitude: (0-10)V (p-p)
