Reply To: How can i apply mechanical vibrations of a known power spectrum ?

Hello,

I just generated a sine function on matlab. I specified the frequency to bo 60Hz and sampling frequency of 200. I evaluated the function at time steps 1/Fs and tabulated this data. so i just inputted arbitrary pressure vs. time data as an input to the pressure on transient structural. To give you a better insight, my model aims to study the effect of snoring induced vibrations on the carotid artery. Two pressure transducers picked up pressure readings inside and outside the artery. Then the data were used to produce the power spectrum. Now my aim is to apply those pressure readings. I want to study the full snoring segment as well as the higher and lower frequency vibrations on their own. I have already tried to filter the power spectrum and do a reverse fourier transform, but i am getting complex numbers.
