Does the length of a Fourier Transform affect the ability to discern a small event in the data?
This is a tricky question to ask, let me clarify. I don't care about when the event happened and I don't care about the resolution of the event (it doesn't have to be some precise measurement) but I want to SEE the event. I realize short events/pulses will affect the results in a weird ways, but it doesn't matter, I just want to know some event/pulse happened. Will the length of an FFT affect how long this event/pulse needs to be before I become aware of it?
