Extreme Signal Indicator

This device indicates the most positive or the most negative of a plurality of input signals E1...E4.

The most positive of the signals causes a lamp 2 to glow. Diodes 4 are located in series with lamps 2. In conjunction with a common load resistor 6, diodes 4 permit current to flow only through the lamp that is associated with the most positive input signal. This signal causes current to flow through the common load resistor 6 by way of the associated lamp and diode.

The voltage drop across the load resistor back-biases the diodes associated with the less positive input signals. This prevents current from flowing through their associated lamps. The resistor 6 is returned to a voltage from a supply 8 which is more negative (less positive) than all the possible input signals.
