Abstract: A system for filtering mechanically-induced signal noise from a speed sensor may include a rotating member having at least one target group radially oriented about a center of the rotating member, an inductive speed sensor configured to sense the at least one target group, and two diode pairs each having a first diode and a second diode. The two diode pairs may be operatively connected to the inductive speed sensor and configured to receive a signal having the mechanically-induced signal noise. The system may also include a resistor connecting the diode pairs, a processor connected in parallel with the resistor and configured to receive a signal from the inductive speed sensor. The processor may be configured to receive a signal having reduced signal noise via the diode pairs, and determine a rotational speed of the rotating member based on the signal having reduced signal noise.
