Detailed Description

Oracle for FIR lowpass filter design via spectral factorization.

Function Documentation

create_lowpass_case()

auto create_lowpass_case ( size_t  N = 48 ) -> std::pair<LowpassOracle, double>

inline

Create a default lowpass filter design case.

Constructs a LowpassOracle with standard filter specs: 48 FIR coefficients, passband ripple 0.025, stopband attenuation 0.125.

Parameters

[in]

N

Number of FIR coefficients (default: 48)

Returns

Pair of (LowpassOracle, initial stopband power S²)
