Question

3-How can digital signal processing affect the quality of sound?

Answer 1

Digital Signal Processing, which is the focus here, can be defined quite simply as the processing of a signal in the digital domain to analyze, measure, and manipulate said signal using mathematical calculations. Digital Signal Processing involves the interchanging of information so that said information can be observed, analyzed, or transformed into a separate form of signal. As you can imagine, this takes place very quickly - the entire process is not even noticed by the user. However, Digital Signal Processing is a critical element of a good headset.

There are a handful of different “parts” that make up a successful DSP system:

1) input and Output. This is the interface to the physical world and other devices. In short, analog signals are converted to digital, processed, and then converted back to the analog domain to interact once again with headset users.

2)DSP chip. The “brain” of a DSP system. All of the necessary calculations and algorithms are performed here.

3) Memory. This is where DSP algorithms are stored.

4) Program memory. Like any memory program, the program memory of a DSP stores the programs needed for data to be translated.

5) Computer Engine. This is the part of DSP that computes all of the mathematical functions that take place during communication.

6) Data memory. Storage space for any information that may need to be processed.
