What are Signals and Systems
Before we dive into the details of Signal and System Book by Ramesh Babu, let us first understand what are signals and systems and why they are important for engineering students. Signals and systems are used in every field of technology, electronics, and engineering[^1^]. They help us to analyze, design, and implement various systems that process information and communicate with each other.
A signal is the representation of a physical \"wave\" expressed as a variable in time-space[^1^]. For example, a signal can be the voltage or current of a circuit, the force in a mechanical circuit, the heat flow in a thermal circuit, or the hydraulic flow in a fluid circuit[^1^]. A signal can be continuous or discrete, periodic or non-periodic, deterministic or random, analog or digital[^2^]. A signal can also be represented in different domains, such as time domain, frequency domain, Laplace domain, etc[^2^].
A system is a process that has an input signal or signals and outputs a different signal or signals[^1^] [^2^] [^3^]. A system can be a mathematical model, a piece of code/software, or a physical device[^4^]. A system can be linear or nonlinear, time-invariant or time-varying, causal or non-causal, stable or unstable[^2^]. A system can also be characterized by its impulse response, frequency response, transfer function, state-space model, etc[^2^].
Signals and systems are then coupled through impulse response, convolution, and response to exponential signals[^5^]. This naturally leads to Fourier series representation of periodic signals and consequently, signal representation in the frequency domain in terms of amplitude and phase spectra[^5^]. Fourier series also helps us to understand the concept of harmonics and bandwidth of signals[^2^]. Furthermore, we can extend the Fourier series to Fourier transform for non-periodic signals and discrete-time Fourier transform for discrete signals[^2^]. These transforms allow us to analyze the frequency content of signals and systems and their properties such as filtering, modulation, sampling, etc[^2^].
Why Should You Read Signal and System Book by Ramesh Babu
