kaira.utils.snr_to_noise_power

kaira.utils.snr_to_noise_power(signal_power: float | Tensor, snr_db: float | Tensor) → Tensor[source]

Convert SNR in dB to noise power given a signal power.

Parameters:

signal_power (Union[float, torch.Tensor]) – Power of the signal.
snr_db (Union[float, torch.Tensor]) – Signal-to-Noise Ratio in decibels (dB).

Returns:

Corresponding noise power for the specified SNR.

Return type:

torch.Tensor
