- Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. A DSP is designed for performing mathematical functions like "add", "subtract", "multiply" and "divide" very quickly.

The goal of a DSP is usually to measure, filter or compress continuous real-world analog signals. Most general-purpose microprocessors can also execute digital signal processing algorithms successfully, but may not be able to keep up with such processing continuously in real-time.
Sep 8, 2024 · Digital Signal Processing, commonly called DSP, involves the manipulation of digital signals to improve their quality and efficiency. It intersects various fields, including audio, telecommunications, and radar engineering.
Digital signal processing dramatically improves the sensitivity of a receiving unit. The effect is most noticeable when noise competes with a desired signal. A good DSP circuit can sometimes seem like an electronic miracle worker, but there are limits to what it can do.

- When Does DSP Matter to You?
For a term so casually used in marketing, DSP is a very complex subject. At a basic level, all digital signal processing does is take a signal---for our purposes, an audio signal---and digitally manipulate it to achieve some sort of desired result. That sounds simple, but the actual processing and algorithms used can be incredibly complex. A simple...
Digital signal processing is capable of doing extraordinary things, but it also has simple uses. When you're listening to a music playlist, for example, many players use DSP to ensure that there aren't massive volume jumps between songs. Analog to digital conversion and digital to analog conversion are another common use case for DSP. Often, the co...
Asking when digital signal processing matters might seem like an odd question, but there are times when it's crucial. For audio, there are certain aspects of products where you should pay close attention to the type of digital signal processing or the manufacturer of the DSP chip.
