torchsig.signals.builders.test.shaped_noise_modulator(bandwidth: float, sample_rate: float, num_samples: int, rng=Generator(PCG64) at 0x7694C485E420) → ndarray

Implements a shaped noise modulator for testing and development.

Parameters:

• bandwidth (float) – the desired 3 dB bandwidth of the signal

• signal_power_db (float) – the desired power of the signal in dB

• sample_rate (float) – the sample rate (must align with CF and BW values)

• num_samples (float) – number of samples of shaped noise to create

• rng (optional) – Seedable random number generator for reproducibility.

Returns:

Shaped noise IQ samples with proper bandwidth and center frequency.

Return type:

np.ndarray
