WebNext Page. Frequency Shift Keying F S K is the digital modulation technique in which the frequency of the carrier signal varies according to the digital signal changes. FSK is a scheme of frequency modulation. The output of a FSK modulated wave is high in frequency for a binary High input and is low in frequency for a binary Low input. WebThe frequency shift keying is the most important digital modulation technique, and it is also known as FSK. A signal has the amplitude, frequency, and phase as properties. Every signal has these three …

Sometimes the carrier change between successive signal values is not abrupt, but progressive, as in the continuous phase modulation (CPM) where the carrier adjustment and the digital signal are not exactly ...
WebThe phase modulation is given by Q(t) I(t) = sinφ(t) cosφ(t) = tanφ(t) or φ(t) = tan−1 Q(t) I(t) The IQ modulator is a universal digital modulator. We can draw a set of points in the IQ plane that represent symbols to transmit. For instance, if we transmit I = 0/A and Q = 0, then we have a simple ASK system (amplitude shift keying).
