What are the energy requirements for digital signals?

Answers

Answer 1

Explanation:

Digital signal is used in communication process to minimize the effect of noise. Digital Signals carry more information per unit time as compared to analog signals. Quality of digital signal is better over long distance transmission. Use of bandwidth is less in case of transmission using digital signals.

A power signal has infinite energy and an energy signal has zero average power.

Answer 2

A power signal's average power is infinite, but an energy signal's average power is zero. The energy requirements for digital signal is zero.

What is digital signal?

A digital signal is one in which data is represented as a series of discrete numbers.

To reduce the influence of noise in communication, a digital signal is utilized. When compared to analog signals, digital signals convey more information per unit time.

The digital signal has a higher quality throughout long distance transmission. The use of bandwidth is reduced when digital signals are sent.

The average power of a power signal is limitless, while the average power of an energy signal is 0.

Hence,the energy requirements for digital signal is zero.
