Title: Noise shaping quantizer
Inventor: MATSUTANI YASUYUKI
IPC: H03M7/36
Filed: 1988-07-29
Abstract: PURPOSE:To simplify the composition of the title quantizer by generating a quantize error output by subtraction between the output and the input of an integrator. CONSTITUTION:A circuit 4 having a function to execute either the subtraction or the addition between an output signal P and an input signal X of an integrator 8 and a terminal 3 to output the result of either the subtraction or the addition are provided, and a quantization error Q of either a comparator or a local quantizer 6 is outputted to the terminal. Namely, a quantize error output A is generated by the subtraction between the output P and the input X of the integrator. Consequently, since the output A is determined by an expression A=P-X, the output A can be calculated before the local quantizer 6 operates. Thus, the existence of a function to hold an integrator output value in quantizer composition, which is necessary for a conventional noise shaping quantizer, becomes unnecessary, and the quantizer 6 can be composed even of an RC integrator except a switched capacitor, etc.
