As an AI language model, I can answer your question about FSK and PSK.
FSK stands for Frequency Shift Keying, which is a modulation technique that uses different frequencies to represent digital data. In FSK, the frequency of the carrier signal is shifted between two or more discrete values, depending on the digital signal being transmitted.
PSK stands for Phase Shift Keying, which is a modulation technique that uses different phases to represent digital data. In PSK, the phase of the carrier signal is shifted between two or more discrete values, depending on the digital signal being transmitted.
Both FSK and PSK are commonly used in digital communication systems, such as radio, television, and satellite communication. They are also used in digital data storage systems, such as CDs and DVDs.
