Why psk is better then fsk and ask?

Phase Shift Keying (PSK) is often considered superior to Frequency Shift Keying (FSK) in terms of bandwidth efficiency and resilience to noise. PSK encodes data by altering the phase of a carrier signal, allowing for higher data rates within the same bandwidth compared to FSK, which changes the frequency. Additionally, PSK is less susceptible to amplitude variations, making it more reliable in environments with signal degradation. Overall, PSK is preferred in many digital communication systems for its efficiency and robustness.
