general_spectrum(a_param, b_param, freq)

Create a spectrum function.

The general omni-directional spectrum formulation is \(S(f) = A f^(-5) e^(-B f^(-4))\).

Return is in units of \(m^2/Hz\).

Parameters:

• a_param (float | ArrayLike) – Parameter \(A\) in the general spectrum equation.

• b_param (float | ArrayLike) – Parameter \(B\) in the general spectrum equation.

• freq (float | ArrayLike) – Wave frequencies in Hz.

Return type:

float | ArrayLike
