Frequently Asked Questions

Q1: What is inside Digital Signal Processing?

A1: Digital signal processing includes a program memory which stores all the program the processing uses to process the data. It also includes data memory which stores information within itself which needs to be processed and compute engine which performs the mathematics processing that accessed the program and data from program memory and data memory respectively. Digital Signal processing also includes input/output which serves a lot of functions to connect the information to the outside world.

Q2: What are the applications of Digital Signal Processing?

A2: Some of the applications of digital signal processing are

• Speech recognition
• Image processing
• High speed MODEM data communication
• Speech synthesis
• Wave form generation
• Filtering
• Speech compression and expansion
