Abstract
A signal detecting device includes a multiplier that multiplies a measurement signal by a reference signal, a filter that filters a multiplication result from the multiplier, a first storage that stores an internal state of the filter; and a second storage that stores a filtering result from the filter. The filter filters the multiplication result using the internal state stored in the first storage. The first storage switches an area in or from which the filter writes or reads the internal state in accordance with an index signal representing a type of amplitude of a time-divisional signal in the measurement signal. The second storage switches an area in which the filtering result is stored in accordance with the index signal.
