hi folks i am very new to this topic but very much interested in it as i m very fond of Fourier transform. So i feel there is some relation between the two and this relation is strong!
so can anybody help me in understanding the Wavelet transform assuming that i m a novice. do not suggest any book to read pls.!!!!!
HI purna,
i am pankaj.i a have also keen interest in WAVELET.simply i am telling to u it is nothing but a very short duration wave that has an average value of zero.
wavelet is a very useful tool in the emerging field of speech and image compression(my final year project is also based in this using MATLAB) and i got iiird rank in my university.
if u want to know more abt this try to this link!!!!!!!!
wavelets are mathematical functions that cut up data into different frequency components and then study each component with a resolution matched to its scale. they have advantageous over the traditional fourier methods in analyzing physical situations where the signal contains discontinuties and sharp spikes
Using wavelet transform also avoids the diadvantages of designing systems using fourier transform (which requires the design to compromise between a good time resolution and a good frequency resolution).
