Peak count frequency
WebUse the findpeaks function to find values and locations of local maxima in a set of data. The file spots_num contains the average number of sunspots observed every year from 1749 to 2012. Find the maxima and their years of occurrence. Plot them along with the data. load ( "spots_num" ) [pks,locs] = findpeaks (avSpots); plot (year,avSpots,year ... WebApr 3, 2024 · You have 1ms per sample, so you should have 1/2*1/1ms=+-500 Hz maximum frequency instead of 100 Hz, since you must discard half of the data by symmetry. So you should have 341 points at 500 Hz max. 2.- You should take the maximum peak as your dominant frequency (should be close to 13Hz: your answer).
