BPSK Modulation Quiz for Electronics and Telecommunication Students

The aim of the experiment is to modulate and demodulate Binary Phase Shift Keying (BPSK) and analyze its spectral characteristics. The specific focus is on understanding and explaining various digital modulation techniques used in digital communication systems and analyzing their performance in the presence of Additive White Gaussian Noise (AWGN).

The equipment required for the experiment includes a BPSK modem, Digital Storage Oscilloscope (DSO), connecting wires, and probes.

The phase-shifted waveform is generated using a 2nd order butterworth filter and an OP-AMP inverter.

<p>In binary PSK modulation, the transmitted signal is a sinusoidal wave of fixed amplitude. It has one fixed phase when the data is at one level, and when the data is at the other level, the phase is shifted by 180 degrees. The modulation involves deriving a sinusoid from a crystal clock using IC4017's and frequency divider, as well as using a 2nd order butterworth filter and an OP-AMP inverter for phase-shifted waveform generation. The transmitter section utilizes IC 4052, an analog switch, to generate the sinusoid and phase-shifted waveform.</p> Signup and view all the answers
