Inside Collection (Course): Digital Signal Processing (Ohio State EE700)

The filterbanks developed in the module on the filterbanks interpretation of
the DWT start with the signal representation

From their definition, we see that the scaling coefficients can be written using a convolution:

Practically speaking, however, it is very difficult to build
an analog filter with impulse response

The most often-used approximation is to set
*correct* for general
*good* filters).
