7.1 INTRODUCTION
In this age of automation when man is going on to moon, space stations for research, communication satellites in space, computation, inter continental ballistic missiles and remote control of energy systems by wireless control using digital signal processors and so on, the ‘processes of signal feedbacks’ play an important role.
As a day-to-day example of biological systems, if one is driving a car, ...
