Abstract

PURPOSE:To make reading easy, by selecting a signal which has been provided extending over the most hours, and displaying it in the following period, in case an input digital signal is varied frequently by influence of a noise. CONSTITUTION:The incoming azimuth of a radio wave is measured momentarily, and a signal showing its azimuth, for example, a digital signal of decimal 3 digits is provided to the terminal P. The lowest rank digit of this digital signal is detected by the decoder B, a high level signal is sent out from the corresponding output terminal in accordance with the values 0, 1... 9, and other output terminals maintain a low level. The signals of the said each output terminal and the clock pulses from the clock pulse generator K are added to the AND gates A0... A9, respectively, and the output pulses are separately counted by, for example, the 10 stage counters C0... C9. The carry signals of each counter are added to the OR gate O, and C0... C9 are reset by its output signals. Also, the output signal of the OR gate O drives the memory M, by which a digital signal at that point is stored, and also the signal stored in the indicator D is displayed at all times.
