b) Differentiate between periodic pulse trains and non-periodic pulse trains in the context of digital signals.
b) Differentiate between periodic pulse trains and non-periodic pulse trains in the context of digital signals.
A basic signal should first be verified by an intermittent pulse train to convert it from constant to discrete-time before being sent as a digital signal.
An electromagnetic or electrical current known as a signal is used to transfer data from one system or network to another. Although it can sometimes take other forms, such as current, a signal in electronics is often a time-varying voltage that is also an electromagnetic wave conveying information.
A digital signal in digital electronics is a pulse train (a pulse amplitude modulated signal), which is a series of electrical or light pulses with fixed-width square waves, each occupying one of two distinct levels of amplitude.
