| Parameter | Description |
|---|---|
| X | signal. |
| Noise | noise signal with the same dimensions as X. |
| Fs | sample rate for spectral SNR estimation. |
| Parameter | Description |
|---|---|
| R | ratio in decibels. |
| NoisePower | linear noise power estimate for direct noise input, or noise power in decibels for spectral estimation. |
snr computes a direct signal-to-noise ratio when a noise vector is supplied. With a scalar sample rate, it estimates sinusoidal SNR from the spectrum.
