ABSTRACT:
A system and method for reducing the amount of electrical noise in a signal produced by a temperature sensor for an appliance which utilizes a running average calculation to provide a more accurate sensor reading in an inexpensive and efficient manner. Consecutive readings obtained by the sensor are digitized and stored in a circular buffer. A running average of the readings stored in the buffer is made upon each new reading and the concurrent erasure of the oldest reading.
