Hi,

I am a new member to this group. I greet every one of you.
I want to find the filter impulse response from the power spectral 
density (PSD) of the output signal. The magnitude of the filter 
frequency response is the square root of the PSD. But there is no phase 
information available. Can anybody tell me how to get the phase 
information and then find the impulse response. 

Thanks and Regards,
Nanda Kishore.
