Peaks of sinc function
WebFeb 16, 2024 · pwidth scales the width of the peaks in the sinc () function. In the call to find_peaks_cwt (), using larger values for widths produces fewer peaks (lower density of … The zero crossings of the unnormalized sinc are at non-zero integer multiples of π, while zero crossings of the normalized sinc occur at non-zero integers. The local maxima and minima of the unnormalized sinc correspond to its intersections with the cosine function. That is, sin(ξ)/ξ = cos(ξ) for all points ξ where the derivative of sin(x)/x is zero and thus a local extremum is reached. T…
