Abstract
A switched noise filter circuit for a skid control system which is adapted to filter out noise signals picked up by the wheel sensors as a result of brake squeal which often occurs at low vehicle speeds. Unfiltered, the sudden termination of a noise signal of this type could be interpreted as a rapid wheel deceleration by the skid control system causing a dumping of the brake pressure, resulting in an inadvertent release of the brakes.
