Recently I read about spectrum analyzer and I understood it a bit except that I have few doubts.
Wikipedia says
"The bandwidth of the band-pass filter dictates the resolution bandwidth, which is related to the minimum bandwidth detectable by the instrument. The smaller the bandwidth, the more spectral resolution. However, there is a trade-off between how quickly the display can update the full frequency span under consideration and the frequency resolution, which is relevant for distinguishing frequency components that are close together"
I couldn't quite understand the reason behind this. Could you please help me in sorting this out?
Thanks in advance.
