Complex wavelets satisfy the analyticity condition—the frequency-domain response is non-zero only on the positive-frequency side and zero on the negative-frequency side—so that the coefficients of the complex wavelet transform directly constitute an analytic signal, whose modulus is the envelope (amplitude) and whose argument is the instantaneous phase.

UnverifiedThe frequency-domain response of a real-valued wavelet is asymmetric, and the positive and negative frequency components interfere with each other, causing oscillation in the energy plot.78% similarUnverifiedThe frequency-domain asymmetry of real wavelets makes their scalograms prone to oscillation, so they are not suitable for direct instantaneous frequency estimation.75% similarUnverified当波纹半波长小于接触区域长度时，唱针无法分辨相邻波峰，输出幅度随频率升高而下降，等效于低通滤波器，这是球形针高频响应不及椭圆针的物理根源73% similarUnverifiedRepresenting Fourier spectral components as structures in a two-dimensional frequency-amplitude space can improve impact-echo defect classification, and this improvement goes beyond the effect of merely smoothing along the frequency axis.71% similarUnverifiedDC offset refers to the centerline of an audio waveform deviating from zero level, which makes the waveform asymmetric, affects the accuracy of feature extraction such as MFCC, and can even introduce low-frequency hum.70% similar
