WebJan 15, 2024 · cwtS1 = cwtft ( {Signal1,dt},'wavelet','morl','scales',scales); This doubt is due to the fact that: when using waveinfo ('morl') it turns out the following real expression: morl (x) = exp (-x^2/2) * cos (5x) but when I do the cwtft of a real signal it gives me as outputs complex coefficients. How is this possible? WebThe Morlet wavelet is suitable for continuous analysis. There is no scaling function associated with the Morlet wavelet. compute the Morlet wavelet, you can enter: [psi,xval] = wavefun('morl',10); plot(xval,psi); title('Morlet Wavelet'); For wavelets associated with a multiresolution analysis,
WebValid values for μ are [3,6]. Valid values for σ are [0.1, 1.2]. Smaller values of σ result in a wavelet with superior frequency localization but poorer time localization. Larger values of …
