Abstract
In a microwave oven, a turn table rotates once in a period TX. During one rotation of turn table, a control circuit usually detects six pulse signals. Control circuit detects a weight of food placed on turn table based on detected intervals TA, TB, and TC of pulse signals. Note that, if six pulse signals are not detected during one rotation of turn table, the control circuit retries detection of the pulse signals and detects the weight of food placed on turn table based on TA, TB, and TC for a subsequent rotation of turn table.
