I am collecting information via the picoscope. My aim is to apply a digital filter over it, and then plot : (spectrum of filtered signal) - (a fixed spectrum saved).
What I want is a real time fft, like the one shown in the picoscope 6 program, but I must process the data first so I need to use matlab instead.
-Gathering data is quite slow. Is the majority of the time taken up by ADC conversion? If I wanted to replicate the picoscope 6 spectrum via matlab, there would be a significant delay. Any suggestions?
-How does the picoscope 6 program show the real time fft? ie how many points does it use, what is the refresh rate, etc? I want to know so I can maybe base my matlab code on it.
Thank you very much.
