Abstract: A ripple circuit includes a sensor, and oscillator circuit and a logic gate. The sensor monitors operation of a motor that is powered by a power signal provided by a motor circuit. The sensor outputs a data signal having a first state or a second state based on the operation of the motor. The oscillator circuit generates an oscillating signal having a fixed frequency. The logic gate includes at least one input in signal communication with the sensor and the oscillator circuit and at least one output in signal communication with the motor circuit. The logic gate selectively outputs the oscillating signal based on the first state or the second state of the data signal to generate a modulated signal. The logic gate is configured to deliver the modulated signal to the motor circuit.
