PURPOSE:To save duration (width) shown by a signal to be binary-coded and to binary-code it, but not to binary-code a noise together, by outputting the first comparison output signal which has an output part coinciding with the second comparison output signal as to its time, and continues to the output part, as a binary-coding output of the signal to be binary-coded. CONSTITUTION:When a signal to be binary-coded is inputted through a line 5, its signal is compared with the first slice level in the first comparing circuit 2, an output signal is generated in its output, and on the other hand, the signal to be binary-coded is compared with the second slice level in the second comparing circuit 3, and an output signal is generated in its output. The output signals of these two comparing circuits 2, 3 are inputted to an operating circuit 4, and among the output signals of the first comparing circuit 2, the signal which coincides with the output signal of the second comparing circuit 3 as to its time and also continues before and after it is outputted as a binary-coding signal of the signal to be binary-coded. |
