engineering recuitment HAL Management & Design Trainee Mock Test 2023 Signals and Systems Laplace Transform
Consider the following statements regarding ROC of Laplace Transform of continuous-time signals:
1. If two signals x1(t) and x2(t) with ROC 'R1' and 'R2' Respectively are added then the ROC of the resultant signal is (R1 U R2).
2. Time differentiation and time-shifting of a signal will not change the ROC of that signal.
3. For time reversal the ROC will also be reversed.
