Lifting Wavelet Transform of Integer-Valued Signal Copy Code Copy Command Specify an integer-valued signal. Create a lifting scheme associated with the db2 wavelet. Get sig = 1:10; lsc = liftingScheme('Wavelet','db2'); Obtain the level 2 lifting wavelet transform (LWT) using the lifting ...
Analyzing a hyperbolic chirp signal (left) with two components that vary over time in MATLAB. Theshort-time Fourier transform(center) does not clearly distinguish the instantaneous frequencies, but thecontinuous wavelet transform(right) accurately captures them.See the MATLAB code. With the discrete w...
