Experiment Name:

To Develop elementary signal function for unit sample, unit step, exponential and unit ramp sequences.

Unit Sample

The definition of unit Sample Seqence is $$ x[n] = \begin{cases} 1 & \mbox{for $n = 0$} \\ 0 & \mbox{elsewhere} \end{cases} $$

Let's implement unit sample by python code

import numpy as np
import matplotlib.pyplot as plt

n = range(-3, 4, 1)
y = []
for i in range(len(n)):
    temp = (1 if n[i] == 0 else 0)
    y.append(temp)
    
plt.stem(n, y)
plt.axis([-3.1, 3.1, -0.1, 1.1])
plt.show()
