Usage:

sig2osp(x, sr, f1, do, n, amin)

Function:

Computes an amplitude spectrum (fft) of the signal x and converts it to an order spectrum.

Parameters:

x

The signal.

sr

The sampling rate of x.

f1

The first order frequency.

do

The order resolution of the result (frequency resolution = do*f1).

n

The number of order lines.

amin

The default amplitude for unassigned order lines.

Result:

An order spectrum with n elements.
