SIG_MACPHERSON2003 - - Stimulus from Macpherson and Middlebrooks (2003)

Usage

sig = sig_macpherson2003(density,depth,phase,dur,fs,flow,fhigh,fmin)

Input parameters

density ripples/oct. Default is 1 r/o.
depth ripple depth (peak-to-trough) in dB. Default is 40 dB.
phase ripple phase in rad. Default is 0.
dur signal duration in seconds. Default is 0.25 seconds.
fs sampling rate in Hz (only required for low-pass filtering). Default is 48 kHz.
flow lower corner frequency of ripple modification in Hz. Default is 1 kHz.
fhigh upper corner frequency of ripple modification in Hz. Default is 16 kHz.
fmin frequency limit of signal energy in Hz. Default is 600 Hz.

Output parameters

sig spectrally rippled noise.

Description

Noise burst with sinusoidal spectral magnitude ripple.
