(English)S&S || Question 1.21(e,f) || Plot the Given Signals

Описание: (English)S&S || Question 1.21(e,f) || Plot the Given Signals
In this video, we solve Signals and Systems – Question 1.21 (e,f) from the famous Oppenheim & Willsky textbook.
You will learn how to plot the given signals, apply time reversal, add signal combinations, and work with impulse (delta) functions and the unit step function.

We break down each part clearly so you can understand:
✔ How to compute
x(t)+x(−t)
x(t)+x(−t)
✔ How
u(t)
u(t) (unit step) affects the signal
✔ How to evaluate impulses at specific time shifts
✔ How to determine impulse amplitudes from the original signal
✔ How to sketch accurate, exam-ready graphs

This is an excellent question for strengthening your basics in:
• Signal transformations
• Time shifting and time reversal
• Scaling and superposition
• Impulse operations
• Piecewise signal representation
