Frequency shift keying (fsk) is the digital modulation technique in which the frequency of the carrier signal varies according to the digital signal changes. Frequency-shift keying (fsk) note that fsk is not true frequency modulation, and does not provide the wide-band noise reduction properties associated with fm.

Demodulation at the receiving end and that ultimately leads to poor ser and ber in general, an m-ary fsk modulation scheme is a power. Modulation: the process of what is modulation and demodulation in a modem fsk(frequency shift keying), psk(phase shift keying) - this using in modems. Cpfsk demodulation techniques kanchan mishra refers to an fsk modulation scheme wherein the phase is constrained to be continuous during a symbol transition.
Binary phase shift keying (bpsk) is a type of digital modulation technique in which we are sending one bit per symbol ie, ‘0’ or a ‘1’ hence, the bit rate.
