What is the output of DWT?

The outputs A and D are the reconstruction wavelet coefficients: A: The approximation output, which is the low frequency content of the input signal component. D: The multidimensional output, which gives the details, or the high frequency components, of the input signal at various levels (up to level 6)

What is the DWT coefficient?

The DWT coefficients represent the degree of correlation between the analyzed signal and the wavelet function at different instances of time; therefore, DWT coefficients contain temporal information of the analyzed signal.

What is the difference between CWT and DWT?

To summarize: The CWT and the discrete wavelet transforms differ in how they discretize the scale parameter. The CWT typically uses exponential scales with a base smaller than 2, for example 21/12 . The discrete wavelet transform always uses exponential scales with the base equal to 2.
