* Lecture 3: Signal Operation

Signal Operation

Course Outline:

• Time Inversion

• Time Scaling

• Time Shifting

• Time Scaling and Shifting (Method I, II, and III)

• Amplitude Reversal and Reversal

• Amplitude Scaling

• Amplitude Shifting

• Amplitude Scaling and Shifting

• Signal Operations - Addition, Multiplication of Signals, 

Note: You should be able to sketch the signals when the signals experience any of the given condition, eg time shifting. You should be able to differentiate between time scaling and amplitude scaling based on the given signal expression.

z(t) = y(2t) --> Time Scaling

z(t) = 2y(t) --> Amplitude scaling
