摘要： A matched filter circuit with a sampling and holding circuits which are classified into two groups. A control circuit successively closes one of switches in the first group every chip time, at the same time, closes one of switches in the second group at a shifted timing by 1/2 chip time from the timing of the first group.

摘要： The present invention has an object to provide a matched filter which can refresh whole of a circuit keeping the speed of a calculation with a small size circuit. The first and second addition circuits of a matched filter of the present invention are classified into a plurality of groups, the first and second auxiliary adders are settled for replacing functions of groups of the first and second adders, respectively, outputs of the first and second adders are input to the first and second subtractors, respectively, the refreshing means appropriately refreshes groups replaced by the first and second auxiliary adders. Further, the present invention decreases the number of auxiliary sampling and holding circuits to be one, and decides the intervals of refreshment with considering the change of voltage caused by leak as well as the permissible error of output voltage.
