What does the abbreviation "PSK" mean?

• A. Packet Signal Keying
• B. Phase Shift Keying
• C. Pulse Signal Knock
• D. Point-to-Point Signal Keying

Answer: (B)

The abbreviation "PSK" stands for Phase Shift Keying. This is a digital modulation technique used to transmit data by varying the phase of a carrier wave. In PSK, the phase of the transmitted signal is shifted to represent data bits. For instance, a common form of PSK is Binary Phase Shift Keying (BPSK), where two distinct phase shifts are used to represent binary values 0 and 1. Phase Shift Keying is particularly favored in radio communications for its efficiency and ability to maintain data integrity in the presence of noise. It allows for high data rates over a limited bandwidth, making it a preferred choice for various digital communication systems, including ham radio operations. The technology is significant in ham radio for digital modes, allowing operators to communicate effectively even in challenging conditions. The other options do not accurately describe PSK or are not recognized terms in digital communications.
