Effect of frequency resolution (FFT/DFT) in analysing the spectrum of an impulse force delivered by a shaker?

After taking the frequency spectrum of an impulse force (from a shaker, sampled from a vibration analysis test), there are noticeable peaks at 50 and 150 Hz (presumably due to some...

Is there any connection between frequency resolution and dirac delta function, with regards to FFT and/or DFT?

During parameter study for a project (signal processing applied in mechanical vibration), when I decrease the frequency to a very low value (less than 200 mHz, for a interested range of frequency...
