Clayton Crockett,Jeffrey W. Robbinsone fashion, onto a waveform appropriate for transmission over the channel. This is the most widely accepted approach to digital communications today, and with reference to the signal space diagrams in Chap. 2, it implies that only two parameters can be adjusted to improve communication system performance: transmitted power and channel bandwidth.

The original digital message sequence can be transmitted using analog modulation methods, such as AMVSB-SC, FSK, PSK, and DPSK, or the transmitted signals can be discrete-amplitude “baseband” pulses.
