In this technique, frequency of the RF carrier is varied in accodance with baseband digital input. The short form of Frequency Shift Keying is referred as FSK. ASK is a bandwidth efficient system but.It has lowest noise immunity against noise.In ASK probability of error (Pe) is high and SNR is less.Refer OOK vs ASK modulation > which compares OOK vs ASK and depictsĭifference between OOK and ASK modulation types with signal diagrams. Known as OOK modulation (On Off Keying modulation). The form of ASK where in no carrier is transmitted during the transmission of logic zero is Here A2 is greater in magnitude compare to A1. Often in ASK modulation, binary-1 is represented by carrier with amplitude-A2 andīinary-0 is represented by carrier with amplitude-A1. no carrier).ĪSK modulation can be represented by following equation: Signal with some amplitude while binary 0 will be represented by carrier of zero amplitude(i.e. As shown in the figure, binary 1 will be represented by carrier The figure depicts operation of ASK modulation. In this technique, amplitude of the RF carrier is varied in accordance with baseband digital input signal. The short form of Amplitude Shift Keying is referred as ASK. Input binary data is referred as modulating signal and Unlike Analog modulation, here input is in digitalīinary form. This page on ASK vs FSK vs PSK provides difference between ASK, FSK, PSK modulation types.Īll these are digital modulation techniques. ASK vs FSK vs PSK-Difference between ASK,FSK,PSK modulation
