Abstract
A device senses changes in a frequency or speed to be displayed. A display control circuit controls the time interval for updating the display, according to the magnitude of a sensed change in the frequency or speed, thereby avoiding flickering of the display, as well as improving the accuracy and up-to-dateness of the frequency or speed displayed.
