Abstract

PURPOSE: To prevent the erroneous display in the digit-up and digit-down by detecting that the count output of the frequency counter gets out of the range of the set frequency and then turning off only the display of the frequency higher than the fixed value via the output.
CONSTITUTION: For the digital frequency display unit, the frequency is not counted for the display of more than the MHz digit but the frequency decided by the signal of the band change-over switch is given. And the count output of frequency counter 13 is displayed for the display of under the MHz digit. Then only the display of the frequency of over the MHz digit is turned off via the output of blanking decoder 23 which detects that the count output of counter 13 gets out of the set frequency. As a result, the erroneous display can be prevented in both the digit-up and digit- down, and also the fact that the count output gets out of the set frequency can be displayed.
