My system measures the speeds of two shafts with quarature encoders. As you can see from the below graph their speeds are fluctuating (I also upload the measurement data).
I need to compare the peak to peak amplitudes of these two shaft speeds in a Simulink model (in Real-time).
I tried to find max and the min values, so I used "Find Extrama" block but it gaves error as "o find a peak the input must have three or more samples per channel".
Same error is also seen when I used findpeaks command in Matlab Function block.
Thanks in advance for any help.
