Introduction

Digital Signal Processing (DSP) is a field of study that deals with the processing and analysis of digital signals. A digital signal is a representation of a continuous-time signal, which is converted into a digital format using an analog-to-digital converter (ADC). The digital signal is then processed using various algorithms and techniques to extract useful information, improve the signal quality, or compress the data.
