Hi ashok
Maybe you can be a bit more specific.
I guess that, a 'radial pulse' is some pulse waveform you are sampling
at some rate Fs[Hz].
Then a FFT can give you a frequency spectrum with a resolution of Fs/N
where
N, are then length of the array you put into the FFT (sample length).
Maybe you mean that this resolution becomes 100Hz in your case, and you
want a higher
resolution.
Well, if thats what you mean, you should increase the sampling rate,
and/or the length of the measurement.
