Abstract
A method of quantifying a particulate matter in an exhaust stream includes the steps of accumulating a particulate matter on a sensor. The sensor provides a signal that varies based upon an amount of the particulate on the sensor. The sensor includes a measurement cycle that includes a deadband zone, followed by an active zone, which is followed by a regeneration zone. The particulate matter is calculated after an end of the deadband zone is reached and prior to an end of the measurement cycle.
