Therefore, any discussion of wavelets begins with the Haar wavelet. Daubechies wavelets are the most popular wavelets. They represent the foundations of wavelet signal processing and are used in many applications. These are also called Maxflat wavelets because their frequency responses have maximum flatness at frequencies 0 and R. This is a very desirable property in some applications. Haar, Daubechies, Symlets and Coiflets are orthogonal wavelets with compact support. These wavelets as well as Meyer wavelets are capable of perfect reconstruction. The Meyer, Morlet and Mexican Hat wavelets are symmetrical in shape. Wavelets are chosen based on their shape and their ability to analyze the signal in a particular application. The Haar wavelet is discontinuous and resembles a step
