Welch FFT

Internal function for calculating the PSD using Welch's method. Hardcoded to use Hamming window.

Usage

welch_fft(data, seg_length, n_fft, noverlap, n_sig, srate)

Arguments

data

Object to perform FFT on.

seg_length

length of each segment of data.

n_fft

length of FFT.

noverlap

overlap between segments.

n_sig

number of samples total.

srate

Sampling rate of the data.
