What is Digital Signal Processing?

Digital signal processing (DSP) is a branch of engineering that deals with the manipulation and analysis of signals using digital techniques. Signals are any physical phenomena that carry information, such as sound, images, video, radar, etc. Digital techniques involve converting signals into binary numbers (0s and 1s) that can be processed by computers or specialized hardware devices.

Definition and Applications

According to , DSP can be defined as "the science of using computers or specialized digital hardware to transform or modify signals". The main goals of DSP are to enhance, compress, filter, transmit, or synthesize signals for various purposes. Some of the applications of DSP include:

  • Audio and speech processing: such as noise reduction, speech recognition, music synthesis, etc.

  • Image and video processing: such as face detection, object recognition, video compression, etc.

  • Wireless communications: such as modulation, demodulation, coding, decoding, etc.

  • Radar and sonar: such as target detection, tracking, classification, etc.

  • Biomedical engineering: such as electrocardiogram (ECG), electroencephalogram (EEG), magnetic resonance imaging (MRI), etc.

Discrete-Time Systems and Signals

A key concept in DSP is that of discrete-time systems and signals. Discrete-time systems are systems that operate on discrete-time signals, which are sequences of numbers that represent the values of a continuous-time signal at equally spaced time intervals. For example, a digital audio signal is a discrete-time signal that represents the sound pressure level at a microphone at regular intervals (such as every 1/44100 seconds). Discrete-time systems can be described by difference equations or by transfer functions that relate the input and output signals. For example, a discrete-time system that adds a constant value to every sample of the input signal can be described by the difference equation y[n] = x[n] + c or by the transfer function Y(z) = X(z) + cZ^-1 , where x[n] and y[n] are the input and output signals respectively, c is the constant value, n is the sample index, and z is the complex variable of the z-transform.

Frequency-Domain Analysis

Another important concept in DSP is that of frequency-domain analysis. Frequency-domain analysis is a method of studying the characteristics of signals and systems in terms of their frequency components. Frequency components are the sinusoidal waves that make up a signal or a system's response. For example, a musical note can be decomposed into a fundamental frequency and its harmonics, which are multiples of the fundamental frequency. Frequency-domain analysis can be performed using various tools, such as the Fourier transform, the discrete Fourier transform (DFT), the fast Fourier transform (FFT), the z-transform, etc. Frequency-domain analysis can reveal useful information about signals and systems, such as their bandwidth, spectrum, frequency response, stability, etc.
