- sdr.crest_factor(x: ArrayLike) float
Measures the crest factor of a signal.
- Parameters:¶
- x: ArrayLike¶
The time-domain signal \(x[n]\) to measure.
- Returns:¶
The crest factor of the signal \(x[n]\).
Notes¶
\[\text{CF} = \frac{V_{\text{peak}}}{V_{\text{rms}}}\]\[V_{\text{peak}} = \max \left( \left| x[n] \right| \right)\]\[V_{\text{rms}} = \sqrt{\frac{1}{N} \sum_{n=0}^{N-1} \left| x[n] \right|^2}\]References¶
