1. Signal Classification and Operations

The book begins with the absolute basics. Rawat does an excellent job of explaining the classification of signals (Continuous vs. Discrete, Even vs. Odd, Periodic vs. Aperiodic). The Highlight: The section on signal operations (time

• The Highlight: The section on signal operations (time shifting, scaling, and reversal) is exceptional. This is a topic where students often make silly mistakes. Rawat uses graphical examples extensively here, teaching the student how to "see" the operation rather than just plug numbers into a formula.

Tools & quick code snippets

• MATLAB/Octave: conv, fft, ifft, filter, zplane, tf, ss
• Python (NumPy/SciPy): numpy.convolve, scipy.signal.freqz, scipy.signal.lti / dlti Example (Python convolution):

import numpy as np
x = np.array([1,2,3])
h = np.array([0,1,0.5])
y = np.convolve(x,h)
print(y)

Exam/assignment strategy

• Show ROC/poles-zeros for transform-based answers.
• For convolution, if analytic integration is messy, show graphical convolution and verify numerically.
• For transform inversions, use partial fraction expansion and list conditions (ROC) that pick the correct inverse.
