Digital signal processing apparatus and method and dither signal generating apparatus.

摘要: A digital signal processing apparatus and a method for carrying out re-quantization process turning an inputted into with smaller bit number includes generator (10) processor (13). The has data (1), delay circuit (2) adder (4) generates dither which amount of high frequency component is larger than that the low component. (1) M-series data-like non-correlating data. delays output from (1). adds polarity been inverted (3). In process, are added (12) then re-quantized
