: Frequency domain analysis for aperiodic signals and its properties. Discrete-Time Fourier Transform (DTFT)
This is where the book shines. Rawat explains Linear Time-Invariant (LTI) systems using the convolution integral and sum. He includes numerous "Trick Problems" where systems appear linear but aren’t, helping students avoid common GATE traps. Signal And System By Tarun Kumar Rawat.pdf

The book occasionally references real-world systems: RC circuits, simple echo filters, and AM modulation. However, it focuses less on software implementation (MATLAB/Python) than some modern texts. For a purely conceptual or exam-oriented study, this is a strength; for a project-based course, instructors might supplement with lab manuals. He includes numerous "Trick Problems" where systems appear
