Operations on Time of Signals

Summary

This video explains key time-related operations on signals, which are fundamental in signal processing. The operations covered include time shifting (moving a signal left or right on the time axis), time scaling (compressing or expanding the signal’s time period), and time reversal (flipping the signal over the vertical axis). The video also emphasizes that time scaling does not apply to unit step functions. The practical implications of these operations are explored in detail, with examples demonstrating the effects of scaling and shifting on signals, particularly in technical contexts such as exams and real-world applications.
