What is Digital Signal Processing?

Discover how digital signal processing (DSP) converts analog signals into discrete-time sequences that can be stored and manipulated. Learn the basics of sampling, the role of algorithms, and how DSP transforms signals using software techniques. This lesson introduces the fundamental concepts behind using digital signals to model, analyze, and apply signals in multiple domains.

We‘ve just learned how the world is driven by natural signals, almost all of which are analog. Now let’s turn toward the power of digital signals.

Exploring DSP

In analog signals, the independent variable of time is represented on a continuous scale. On the other hand, a discrete-time signal is a sequence of samples that can be stored in computer memory and operated on with a processor. Sampling is the process through which analog signals are sampled at regular intervals to produce a discrete-time signal. ...
