Frequency response of a mirror-image time response

Hello all, this is the first time to post.

I have some sampled s-domain frequency response f of a continuous time
system, which represents a time-response h(T_s), h(2 T_s)..., h(N T_s). So
what is the frequency response for a mirror-image time response (i.e. h(N
T_s) ... h(2 T_s), h(T_s)). I have no idea how to obtain. Is there anybody
can help me?

Thanks.

Leon

Hello Leon,

Welcome. Look up for fourier transforms the scaling property and the
conjugation property.  I think you can find the answer now. Hint the
magnitude response will be unaffected.
