Holmz Posted September 15, 2021 Share Posted September 15, 2021 I was reading about current source versus voltage source amplifiers and I may be a bit confused. When we see impedance versus frequency, how are those values determined? Is it a steady state measurement or a swept chirp? And then what happens for say from a pure delta Dirac type of impulse or for a step? If the speaker has a graph the sensitivity as a function of the frequency, does the actual FFT of the speaker’s measured impulse differ from the FFT of the input voltage by exactly the same amount as the it’s sensitivity graph would show? I guess it must? Quote Link to comment Share on other sites More sharing options...
