Abstract

A signal level indicator (204, 304) displays the magnitude of an input signal (421) by illuminating each of a number of five LEDs (314-318, 414-418) for an individual period of time. The number of LEDs to be illuminated and the individual period of time that each is to be illuminated varies with the magnitude of the input signal (421).
