We take a look at some of the fundamentals of Digital Signal Processing. What is DSP? Digital Signal Processors (DSP) take real-world signals like audio, video, voice, temperature, position or pressures that are digitized and then accurately manoeuvre them. It is designed for performing mathematical functions like subtract, add, divide and multiply very quickly.
How they work Signals from real world sources are converted by Digital Signal Processing into digital data that can then be analyzed. The signals will be usually in analog form. Study is performed in digital form because when we reduce a signal to numbers its mechanism can be manipulated in more detail than when they are from real world sources.
