... used here to refer to them. Each edoc isconverted to a prefix code that’s output. The first table allocates edocs 0 through 255 to the literals, edoc 256 to end-of-block, and edocs 257–285 to lengths. ... frequency.It is also possible to modify this transform to conserve the energy of the datavector. All that’s needed is to multiply the transformation matrix W by the scalefactor 1/2. Thus, the product ... quantization, it is still possible to get back a vector very similar to the original d.We first quantize t to the integers (9, 1,−3, 0) and perform the inverse transform to get back (3.5, 6.5, 5.5,...
