Dear All,

i need to deconvolve the output of a seismometer (sensor) to obtain the structure response.

The known data are the output of the sensor and the transfer function of the sensor that is: s^2/s^2+Q/w0*s+w0^2.

Can i use the deconv command in time domain?

I wrote the following code:

num=[1 0 0];

den=[1 0.25 625];

y1=tf(num,den);

y2=lsim(y1,Data_Channel(5,:),t(1:1200000));

for i=1:length(t)-1

[dec(i) r]=deconv(y2(i),Data_Channel(1,i));

end

plot(dec)

Thank you for your support.

Regards,

Alessio
