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.
