Frequently Asked Questions on DSP Notes

Question 1.
Explain Digital Signal Processing? Why is signal processing essential?

Answer:
Digital Signal Processing is a process of taking real-life signals like audio, video, pressure, or temperature that are digitalized and then manipulating them mathematically. A DSP is specially designed to perform mathematical functions, like, subtract, multiply, divide, and add.

Signals must be processed for ensuring that the stored information displays, analyzes, or converts easily to some other type of signal. Analogue products are generally used for detecting signals of light, sound, pressure, or temperature, and then manipulates them, like the conversion from analogue to digital.

Question 2.
What goes inside a DSP?

Answer:
A DSP contains several vital components, which are as follows:

  1. Program Memory – This unit stores the processing data for the DSP.
  2. Data Memory – This unit is used for storing the information to be processed.
  3. Compute Engine – This part performs the mathematical operations, and then it accesses the program from the program memory and data from the data memory.
  4. Input or Output – This serves several functions for connecting to the outer world.
