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
