Generation and plotting of all basic signals

The following code generates basic signals such as: 1. Unit Impulse 2. Unit Step 3. Unit Ramp 4. Exponential Growth 5. Cosine

The following code generates basic signals such as:

1. Unit Impulse Signal: The unit impulse function can be regarded as a rectangular pulse with a width of and height (1 / ). As tends to 0 the function approaches the Unit Impulse function and its derivative becomes narrower and higher and eventually a pulse of infinitesimal width of infinite height.

2. Unit Step Signal: Unit step function is denoted by u(t). It is defined as u(t) = {1t⩾00t<0. It is used as best test signal. Area under unit step function is unity.

3. Unit Ramp Signal: If the unit step function is integrated with respect to time t, then the unit ramp function results. It is symbolized by r(t). A unit ramp function increases linearly with time. [1]

4. Exponential Growth Signal: The “exponential” signal literally represents an exponentially increasing or falling series: Continuous time: s(t)=eαt. Note that negative α values result in a shrinking signal, whereas positive values result in a growing signal. [2]
