I have samples of a signal varying form 100MHz to 110MHz. How do i plot the frequency response of this signal? I tried fvtool() and fft(). But these plots give me NORMALIZED frequency response. Is there any other method to plot the absolute freq response?

On the fvtool menu bar, you can click Analysis -> Sampling Frequency to specify the sampling rate. fvtool will then scale the frequency axis according to the sampling rate.
