An electronics for active cancellation of a pulsating flow with a source noise reference. The electronics includes a signal processor configured to receive a noise source signal and a flow signal. The signal processor is also configured to generate a cancelling signal based on the noise source signal and the flow signal. A controller is communicatively coupled to the signal processor, and configured to determine a flow rate control signal for controlling the flow rate of the pulsating flow. A signal generator coupled to the signal processor and the controller is configured to receive the flow rate control signal, generate a valve signal based on the flow rate control signal and the cancelling signal, and provide the valve signal to a valve to control the flow rate and attenuate the one or more pulses of the pulsating flow.
