sdr.rms_voltage(x: NDArray, db: bool = False) → float

Measures the root-mean-square (RMS) voltage of a time-domain signal \(x[n]\).

\[V_{\text{rms}} = \sqrt{\frac{1}{N} \sum_{n=0}^{N-1} \left| x[n] \right|^2}\]

Parameters:
x: NDArray

The time-domain signal \(x[n]\) to measure.

db: bool = False

Indicates whether to return the result in decibels (dB).

Returns:

The root-mean-square voltage. If db=False, \(V_{\text{rms}}\) is returned. If db=True, \(20 \log_{10} V_{\text{rms}}\) is returned.
