Title:
DIGITAL SIGNAL PROCESSING CIRCUIT AND DIGITAL CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2010/038278
Kind Code:
A1
Abstract:
Provided are a digital signal processing circuit which attains digital control corresponding to analog PID control by combining a first filter which conducts moving average processing and so on and a second filter circuit which conducts lowpass processing and so on, and a digital control circuit in which the processing circuit is mounted. The digital signal processing circuit (11) is characterized by comprising a moving average circuit (111A) which has a digital value X inputted thereto, a differentiating circuit (112) which has the digital value inputted thereto and conducts differentiation processing , and an adding circuit (113) which generates a signal of adding an output from the moving average circuit (111A) and that from the differentiating circuit (112), thereby compensating the delay of a phase generated in the moving average circuit (111A) by means of the output from the differentiating circuit (112).
