Give the mathematical representation of the following basic signals,

1. Unit Impulse
2. Unit Step
3. Unit Ramp

Plot these signals and their following variants (whichever is applicable).

1. Time Scaled
2. Amplitude Scaled
3. Time Shifted
4. Amplitude Shifted
5. Time reversed
6. Amplitude reversed

Transcribed Image Text:

Note: Each step should also be coded in MATLAB where -7<t≤7 (sec) and keep a step size of 0.001. Label the x-axis as Time (sec), y-axis as amplitude or whatever is feasible. The title should be the signal you plot e.g., x(t+2) and it must change automatically with each entry e.g., if only time scaling is performed then it should be x(at), where a is the scaling unit, if only magnitude shifting is performed then k+x(t) and so on. Remember the LineWidth should be exactly 2. If you plot more plots on the same figure then differentiate them with different colours, markers and legend on an optimal position. Font to be used for the title and labels is "Lucida Bright". The axis (x and y-axis) ticks must adopt with the signal e.g., ymax = max(x(t))+1 and ymin = min(x(t))+1.
