Introduction to Digital Signal Processing Notes

DSP or Digital Processing Signal is the approach that processes data and signals to analyse, enhance, or even modify these signals to ascertain the specific information content. DSP involves the process of the real-world signals which are represented and converted by a sequence of numbers.

Digital Processing Signal manipulates the different types of signals to measure, produce, compressing, or to filter the analogue signals. The DSP captures digitised signals like video, pressure, voice, or even temperature to operate them mathematically. The information is represented as discrete frequency, or discrete-time, or any other discrete forms so that the information gets digitally processed.
