Discrete-Time Signal Representation

Question

x1[n] is made of random 8 digits for -3 <= n <= 4 and zero is elsewhere.

can anybody help me create this in python?

Answer 1

import numpy as np
import matplotlib.pyplot as plt

# Define the discrete-time index range
n_min, n_max = -3, 4
n = np.arange(n_min, n_max + 1) # Generate discrete-time indices

# Generate random values for x1[n] within the given range
x1 = np.random.randint(0, 10, size=len(n)) # Random digits (0-9)

# Plot the discrete-time signal
# Remove 'use_line_collection=True' since it's not supported in older Matplotlib versions
plt.stem(n, x1)
plt.xlabel('n')
plt.ylabel('x1[n]')
plt.title('Discrete-Time Signal x1[n]')
plt.grid(True)
plt.show()

# Print the generated sequence
print("n values:", n)
print("x1[n] values:", x1)
n_min, n_max = -3, 4
n = np.arange(n_min, n_max + 1) # Generate discrete-time indices

# Generate random values for x1[n] within the given range
x1 = np.random.randint(0, 10, size=len(n)) # Random digits (0-9)

# Plot the discrete-time signal
# Remove 'use_line_collection=True' since it's not supported in older Matplotlib versions

Answer 2

plt.stem(n, x1)
plt.xlabel('n')
plt.ylabel('x1[n]')
plt.title('Discrete-Time Signal x1[n]')
plt.grid(True)
plt.show()

# Print the generated sequence
print("n values:", n)
print("x1[n] values:", x1)
