Location: signal/response_signals.py

Description

generate_semi_periodic_signal creates a semi-periodic digital signal by repeating a given binary pattern and introducing random bit flips. This function is useful for modeling schedulled interruptions with possible delays.

Notes

  • Increasing flip_probability increases randomness, making the signal less periodic.
  • The function repeats base_pattern as needed and truncates to the required length.
  • Setting a seed ensures consistent signal generation across multiple runs.

Parameters

  • length (int, optional): The total length of the generated signal (default: 450).

  • base_pattern (list of int, optional): A binary sequence representing the repeating base pattern.

  • If None, defaults to [0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1].

  • flip_probability (float, optional): The probability of flipping each bit to simulate signal variations (default: 0.1).

  • seed (int, optional): Random seed for reproducibility (default: None).

Returns

  • semi_periodic_signal (numpy.ndarray):
    The generated semi-periodic binary signal.

Usage Example

import numpy as np
import SigVarGen as svg

# Generate a semi-periodic signal with a bit flip probability of 5%
semi_periodic_signal = svg.generate_semi_periodic_signal(length=300, flip_probability=0.05)

print("Generated Signal:", semi_periodic_signal[:20])  # Print first 20 samples
