Web4.1. Amplitude shift keying (ASK) Amplitude shift keying (ASK) is the simple form of digital modulation. Digital input is unipolar NRZ signal. WebFor example, in the case of QPSK modulation and AWGN channel, the BER as function of the Eb/N0 is given by: = (/). People usually plot the BER curves to describe the performance of a digital communication system.
