ABSTRACT:
A wavelet transformation apparatus including a unit that comprises a first adding device that adds a first input signal and a second input signal input by a predetermined order, a first multiplying device that multiplies an output of the first adding device with a coefficient; a second adding device that adds a fixed value to the output of the first adding device, a first switching device that switches the output of the first adding device and an output of the second adding device; a second multiplying device that multiplies an output of the first switching device with a coefficient, a second switching device that switches an output of the first multiplying device and an output of the second multiplying device, and a third adding device that adds a third input signal of a predetermined order to an output of the second switching device.
