Correct option is (a) True
For explanation: It is true. A wavelet transform is almost always implemented as a bank of filters that decompose a signal into multiple signal bands. Wavelets are a relatively new signal processing method. Thus, one of the biggest advantages of using the wavelet transform is that signal features can be easily extracted. In many cases, a wavelet transform outperforms the conventional FFT when it comes to feature extraction and noise reduction. predictable, and software simulations can exactly reflect product performance.
