Why do we need to study modulation and demodulation in communication system?

While modulation helps in the collection of data into the carrier, demodulation helps in the recovery of data.

What is PSK modulation and demodulation?

Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave). The modulation is accomplished by varying the sine and cosine inputs at a precise time.

What is modulation and demodulation in simple words?

Modulation is the process of encoding information in a transmitted signal, while demodulation is the process of extracting information from the transmitted signal.

Which coding technique is usually used in PSK modulation?

BPSK (Binary Phase Shift Keying) – a coherent modulation technique that requires synchronization between the transmitter and the receiver using two phase values: –180° and +180°, encoded as a single bit in the binary code as a logical 0 or 1.
