Title:
WINDOW FUNCTION PROCESSING MODULE
Document Type and Number:
WIPO Patent Application WO/2017/167297
Kind Code:
A1
Abstract:
Provided is a window function processing module (90), comprising: an integrating circuit (94) used for receiving an integration input signal (VIN) and comprising an operational amplifier (Amp); an integrating capacitor (CI) coupled to an output end and a first input end of the operational amplifier (Amp); an variable impedance module (VI), coupled between the first input end of the operational amplifier (Amp) and an integration input end of the integrating circuit, and controlled by at least one control signal (ctrl) to adjust an impedance value of the variable impedance module (VI); and a control unit (96), coupled to the integrating circuit (94) and used to generate the at least one control signal (ctrl) according to a window function, to adjust an integration gain of the integrating circuit (94), so that an integration output signal is correlated with an operation result of the integration input signal and the window function.
