sdr.peak_power

sdr.peak_power(x: ArrayLike, axis: int | tuple[int, ...] | None = None, db: bool = False) → float

Measures the peak power of a time-domain signal $x [n]$ .

P_{peak} = max {| x [n] |}^{2}

Parameters:¶

x: ArrayLike¶: The time-domain signal $x [n]$ to measure.
axis: int | tuple[int, ...] | None = None¶: Axis or axes along which to compute the peak power. The default is None, which computes the peak power of the entire array.
db: bool = False¶: Indicates whether to return the result in decibels (dB).

Returns:¶

The peak power. If db=False, $P_{peak}$ is returned. If db=True, $10 \log_{10} P_{peak}$ is returned.
