Why is digital signal processing needed?

The purpose of digital signal processing is, as mentioned before, to filter analog signals from current time and space. It is used in a wide variety of technological equipment but is an especially critical aspect of noise suppression and voice enhancement communication equipment.

What do you mean by digital signal processing?

Digital signal processing (DSP) refers to various techniques for improving the accuracy and reliability of digital communications. The theory behind DSP is quite complex. Basically, DSP works by clarifying, or standardizing, the levels or states of a digital signal.

Which is a typical application of digital signal processing?

DSP applications include audio and speech processing, sonar, radar and other sensor array processing, spectral density estimation, statistical signal processing, digital image processing, data compression, video coding, audio coding, image compression, signal processing for telecommunications, control systems, ...
