signal-ICT-KaavyaRao-92510133009 1.0.0

A Python package for fundamental signal processing operations

This Package demonstrates the fundamental concepts of Signals and Systems by implementing various unitary signals, trigonometric signals, and signal operations in a modular way. The project also includes a main.py script that showcases how to use these modules with the help of tasks.

Modules and Functions

1. unitary_signals.py Implements basic discrete signals:

• unit_step(n) - Generates a unit step signal.
• unit_impulse(n) - Generates a unit impulse signal.
• ramp_signal(n) - Generates a ramp signal.

Each function:

• Returns a NumPy array
• Plots the signal using Matplotlib

---

2. trigonometric_signals.py Implements continuous-time signals:

• sine_wave(A, f, phi, t) - Generates a sine wave
• cosine_wave(A, f, phi, t) - Generates a cosine wave
• exponential_signal(A, a, t) - Generates an exponential signal

---

3. operations.py Implements signal operations:

• time_shift(signal, k) - Shifts signal by k units
• time_scale(signal, k) - Scales time axis by factor k
• signal_addition(signal1, signal2) - Adds two signals
• signal_multiplication(signal1, signal2) - Multiplies two signals point-wise

---

Main Script (main.py) Demonstrates:

1. Generate and plot unit step and unit impulse signals (length = 20).
2. Generate and plot a sine wave (A=2, f=5 Hz, phase=0, t=0–1 sec).
3. Perform time shifting on sine wave (+5 units).
4. Perform addition of unit step and ramp signal.
5. Multiply a sine and cosine wave of same frequency.
