Question:
Time scaling is an operation performed on:
Time scaling is an operation performed on:
Show Hint
Time scaling affects only the independent variable (time) in a signal, not the dependent variable (amplitude).
Updated On: May 4, 2025
- Dependent variable
- Independent variable
- Both dependent and independent variables
- Neither dependent nor independent variable
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Time scaling involves stretching or compressing the time axis of a signal. It is typically performed on the independent variable (time) in a signal, not on the dependent variable (amplitude). This operation changes the time duration of the signal but does not affect the nature of the signal itself.
Thus, time scaling is an operation performed on the independent variable.
