ASK (Amplitude Shift Keying)
ASK is a form of modulation that represents digital data as variations in the
amplitude of a carrier wave. The amplitude of an analog carrier signal varies
in accordance with the bit stream (modulating signal), keeping frequency and
phase constant. The parameters for the ASK are as shown in Figure 2- 32

Term Explanation
Frequency Deviation
��
The deviation should be equal to or less than the carrier waveform
frequency.
��
The sum of the deviation and the carrier frequency should be equal to
or less than maximum frequency of the selected function.
