Abstract:

Digital to analog conversion of signals uses digital modulation techniques because of reasons such as its capacity to store huge amount of data, high security. Amplitude shift keying is a technique where the amplitude of the output depends on the input data and it is zero level when the input bit is 0 or is variation of positive and negative depending on carrier frequency when the input is 1.

Objectives:

• The modulation of the input digital signal to corresponding amplitude shift keying output.

• Demodulation of the output amplitude shift keying to corresponding digital signal.

• Probability of the bit error rate with respect to snr (signal to noise ratio).

• Comparison of amplitude shift keying with other Shift keying methods.
