Abstract
An LED bar graph display is disclosed, which can simultaneously display signal strength and diagnostic information. When an input signal is received, the indicators are selectively operated to display a strength value of the input signal. When a diagnostic condition occurs, the indicators are selectively operated to display the diagnostic condition. Thus, the LED bar graph display performs the dual functions of displaying signal strength and diagnostic information.
