Abstract
PURPOSE:To make possible to judge a state correctly by processing signals so that noise alone may be removed and signals may be displayed on a CRT or recorded in the form of their proper received levels unchanged. CONSTITUTION:When effective signals and randomly arriving noise exist together in received signals, a signal A previously received and a signal B received this time are A/D converted in n bits and stored in memory circuits 6 and 7. By comparing the outputs of the memory circuits 6 and 7 with a comparing circuit 8, gate circuits 9 and 10 are controlled so that the received signal A may be taken out when A<B, the received signal B may be taken out when A>B and the received signal A or B may be taken out when A=B.
