Latest Patents

Yukio Fukuhara holds a patent for a noise shaper. This invention features a pole-shifted noise shaper whose transfer function has a Z-plane in which the pole has been shifted out of the origin. The noise shaper effectively suppresses idle patterns. It incorporates a dither adder placed immediately before a quantizer to add a dither signal to data about to be applied to the quantizer. This design suppresses the attenuation of the dither signal due to noise shaping, allowing the dither signal to be supplied effectively. The output signal's idle pattern can be suppressed, and the frequency of the noise component due to the dither signal is lowered by varying the dither signal pattern at a frequency that is {fraction (1/16)} to ⅛ of the operating clock signal. This allows for easy separation of the signal and the dither signal component in a rear stage.
