1. A ripple circuit comprising:
a sensor including a first input configured to receive a power signal generated by a motor circuit via a power lead which provides a power signal to the sensor and a motor, the sensor configured to monitor operation of a motor that is powered by the power signal provided by the motor circuit, and to output a data signal having a first state or a second state based on the operation of the motor;
an oscillator circuit configured to generate an oscillating signal having a fixed frequency; and
a logic gate including a first input in signal communication with the sensor to receive the data signal, a second input in signal communication with the oscillator circuit to receive the oscillating signal, and at least one output in signal communication with the power lead of the motor circuit, the logic gate configured to selectively output the oscillating signal based on the first state or the second state of the data signal to generate a modulated signal,
wherein the logic gate is configured to deliver the modulated signal to the motor circuit, and
wherein the logic gate feeds back the modulated signal to the power lead to combine the modulated signal with the power signal,
wherein the sensor is a Hall Effect Sensor (HES) configured to detect one or both of a rotational position (θ) and a rotational speed (ω) associated with the motor, and
wherein the logic gate is an AND gate including the first input configured to receive the data signal from the HES, the second input configured to receive the oscillating signal from the oscillator circuit, and an output configured to deliver the modulated signal to the motor circuit.
