Chapter 5 - Basic Signals And Waveform Synthesis
5.1 INTRODUCTION
A signal is a physical quantity, or quality, which conveys information. Electrical
engineers normally consider a signal to be an electric current or voltage,
and these currents and voltages are functions of time. The step, ramp,
impulse, exponential, and sinusoidal functions, etc., are the basic signals.
These signals may be combined by addition or subtraction to build a variety
of general waveforms used in practice.
Signals play an important role in life. They are used in communication,
speech processing, medical science, etc.
