starting point for the study of modulation. A type of DSB, called binary phase-shift keying, is used for digital telemetry. Amplitude modulation (AM) is similar to DSB but has the advantage of permitting a simpler demodulator, the envelope detector. AM is used for broadcast radio,

Analog Transmission of Digital Data: ASK, FSK, PSK, QAM

www.eecs.yorku.ca

Modulation of Digital Data: ASK 5 ASK – strength of carrier signal is varied to represent binary 1 or 0 • both frequency & phase remain constant while amplitude changes • commonly, one of the amplitudes is zero • demodulation: only the presence or absence of a sinusoid in a given time interval needs to be determined • advantage: simplicity • disadvantage: ASK is very susceptible …
