What is central frequency of wavelet?
wavelet central frequency is that which describes its general behavior, determined by approximating the wavelet to a sine wave and taking its frequency. Fig. 3 shows the Morlet wavelet central frequency, which is one of the most used mother wavelets to determine the electrical signals' frequency content [17].
Is wavelet transform in frequency domain?
The continuous wavelet transform (CWT) is a time-frequency transform, which is ideal for analyzing nonstationary signals. A signal being nonstationary means that its frequency-domain representation changes over time.
What is a wavelet spectrum?
Wavelet Transform (WT) is one of the recent techniques for processing signals. It is defined as mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale [1].
What are the types of wavelet?
There are two types of wavelet transforms: the continuous wavelet transform (CWT) and the discrete wavelet transform (DWT). Specifically, the DWT provides an efficient tool for signal coding.
