sdr.average_power(x: ArrayLike, db: bool = False) → float

Measures the average power of a time-domain signal \(x[n]\).

\[P_{\text{avg}} = \frac{E}{N} = \frac{1}{N} \sum_{n=0}^{N-1} \left| x[n] \right|^2\]

Parameters:
x: ArrayLike

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

db: bool = False

Indicates whether to return the result in dB.

Returns:

The average power. If db=False, \(P_{\text{avg}}\) is returned. If db=True, \(10 \log_{10} P_{\text{avg}}\) is returned.
