An electronics (100) with a DCC adaptive filter (112) for attenuating noise in a feedback path of a flow controller is provided. The electronics (100) includes a signal processor (110) configured to receive a flow signal (220a) from a flow sensor (220), the flow sensor (220) is configured to measure a flow rate of a pulsating fluid flow, receive a constant reference signal (112c), and generate a flow rate signal (110a) using the constant reference signal (112c) and the flow signal (220a). The electronics (100) also includes a controller (120) communicatively coupled to the signal processor (110), which is configured to generate a flow rate control signal (120a) using the flow rate signal (110a). The electronics (100) additionally includes a signal generator (130) communicatively coupled to the controller (120). The signal generator (130) is configured to receive the flowrate control signal (120a), generate a valve signal (130a) based on the flow rate control signal (120a), and provide the valve signal (130a) to a valve (210) to control the flow rate of the pulsating flow. |
