The wavelet morl is not valid

WebThe complex Morlet wavelet ( "cmorB-C" with floating point values B, C) is given by: ψ ( t) = 1 π B exp − t 2 B exp j 2 π C t where B is the bandwidth and C is the center frequency. Gaussian Derivative Wavelets ¶ The Gaussian wavelets ( "gausP" where P is an integer between 1 and and 8) correspond to the Pth order derivatives of the function: WebWavelets are not time domain constant – a KERNEL that can extract both frequency and time Still have assumption of temporal stability to deal with, but now the EEG signal only …
