Figure 1.2 (p. 3)
Elements of a communication system. The transmitter changes the
message signal into a form suitable for transmission over the channel.
The receiver processes the channel output (i.e., the received signal) to
produce an estimate of the message signal.

Figure 1.4 (p. 7)
Block diagram of a feedback control system. The controller drives the
plant, whose disturbed output drives the sensor(s). The resulting feedback
signal is subtracted from the reference input to produce an error signal e(t),
which, in turn, drives the controller. The feedback loop is thereby closed.

shifts the output signal y[n] by one sampling interval, producing y[n – 1].
The feedback coefficient p determines the stability of the filter.
