In SI units, angular frequency is normally presented in radians per second, even when it does not express a rotational value. The unit hertz (Hz) is dimensionally equivalent, but by convention it is only used for frequency f, never for angular frequency ω. This convention is used to help avoid the confusion that arises when dealing with quantities such as frequency and angular quantities because the units of measure (such as cycle or radian) are considered to be one and hence om… WebI have created its impulse response through a convolution with a unit pulse. Now I want to plot the frequency spectrum. I perform zero-padding and windowing with a blackman-window. This does not seem to have a big effect on my result though. Still, I wonder: For some reason my amplitude of the resulting spectrum is not normalized correctly.

However, that's not the result of the exact fourier transform, which should be: X ( f) = 2.5 ( δ ( f − f c) + δ ( f + f c)) That is, I expect the amplitude to increase as the frequency bin shrinks (with the total area remaining at 2.5).
