Pulse SignalĪ Pulse shape is formed by a rapid or sudden transient change from a baseline value to a higher or lower level value, which returns to the same baseline value after a certain time period. In this chapter, we are going to discuss pulse signals and their characteristic features. Unidirectional Signal − The signal when flows only in one direction, which is either positive or negative, such a signal is termed as Unidirectional signal.īidirectional Signal − The signal when alters in both positive and negative directions crossing the zero point, such a signal is termed as a Bidirectional signal. These signals are mainly of two types named as Unidirectional and Bidirectional signals. Such a shape of the signal when formed according to a certain variation, can be given different names, such as sinusoidal signal, triangular signal, saw tooth signal and square wave signal etc.
This representation brings some shape to the information conveyed or to the signal received. It also provides information regarding the voltage, frequency, time period, etc. The graphical representation of an electronic signal gives information regarding the periodical changes in the parameters such as amplitude or phase of the signal. Electronic SignalĪn electronic signal is similar to a normal signal we come across, which indicates something or which informs about something. Hence, we will start this tutorial with a brief introduction to signals. The functioning of any circuit can be studies by the signal it produces.
A Signal not only carries information but it also represents the condition of the circuit.
