kaira.utils.noise_power_to_snr

kaira.utils.noise_power_to_snr(signal_power: float | Tensor, noise_power: float | Tensor) → Tensor

Calculate SNR in dB given signal and noise power.

Parameters:

• signal_power (Union[float, torch.Tensor]) – Power of the signal.

• noise_power (Union[float, torch.Tensor]) – Power of the noise.

Returns:

Signal-to-Noise Ratio in decibels (dB).

Return type:

torch.Tensor

Raises:

ValueError – If noise_power contains zero values.
