PURPOSE:To suppress interference waves and to avoid the loss of hit number against required signals and to emphasizes the amplitude, by providing two types of criterion discriminating circuits and a peak hold circuit. CONSTITUTION:An N sweep memory 5 is connected to an output terminal of a comparison circuit 3 where an input signal and a reference value are inputted, and the 1st discrimination circuit 11 and the 2nd discrimination circuit 12 are connected to the output termlnal of the memory 5. A suppression controlling circuit 15 is connected to the output terminal of the circuits 11, 12. A suppression controlling signal 19 is picked up at the output terminal of the circuit 15. The signal 19 is given to the control terminal of a peak hold circuit 16. An input signal 1 is added to the input terminal of the circuit 16 and a peak hold output signal 17 is picked up at the output terminal. The output terminal of the circuit 16 is connected to the input terminal of the circuit 8 and an output signal is picked up from the output circuit of the suppressing circuit 8. |
