Plural channel monitor displaying a.c. or d.c. information signals as a bar graph on an oscilloscope

Claim 1

A DISCRIMINATOR MONITOR FOR SIMULTANEOUSLY MONITORING ON AN OSCILOSCOPE HAVING A VERTICAL DEFLECTION INPUT A MULTI-CHANNEL TELEMETRY RECEIVER SYSTEM WHEREIN SAID SYSTEM CONSISTS OF A MULTIPLICITY OF DISCRIMINATOR CHANNELS, EACH OF SAID CHANNELS CONSISTING OF BAND PASS FILTER SECTION AND A DETECTOR SECTION, COMPRISING: A STAIR STEP GENERATOR FOR GENERATING A REPETITIVE STAIR STEP VOLTAGE SIGNAL, EACH SIGNAL HAVING A STEP FOR EACH OF SAID CHANNELS OF SAID TELEMETRY SYSTEM, SAID GENERATOR CONNECTED TO SWEEP A BEAM HORIZONTALLY ACROSS THE FACE OF SAID OSCILLOSCOPE IN SYNCHRONIZATION WITH SAID STAIR SIGNAL; A PULSE GENERATOR FED BY SAID STAIR STEP SIGNAL TO PROVIDE A PULSE OUTPUT FOR EACH STEP OF SAID STEP SIGNAL; A TUMBLECOUNTER ELECTRONIC SWITCH ACTUATED BY SAID PULSE GENERATOR, SAID ELECTRONIC SWITCH HAVING A MULTIPLICITY OF ISOLATED SWITCHING CHANNELS, SAID TUMBLECOUNTER FUNCTIONING AS A SEQUENTIAL SCANNING MEANS; A MODE SELECTOR SWITCH HAVING A MULTIPLICITY FO CHANNELS, EACH OF THE SWITCH CHANNELS HAVING TWO INPUTS AND ONE OUTPUT, ONE OF THE INPUTS OF EACH OF SAID MODE SWITCH CHANNELS CONNECTED TO THE OUTPUT OF THE BAND PASS FILTER OF ONE OF SAID TELEMETRY CHANNELS AND THE OTHER INPUT OF EACH OF SAID MODE SWITCH CHANNELS CONNECTED TO THE OUTPUT OF THE DETECTOR PORTION OF THE SAME TELEMTRY CHANNELS, THE OUTPUT OF EACH CHANNEL OF SAID MODE SELECTOR SWITCH CONNECTED TO THE INPUT OF A CHANNEL OF SAID ELECTRONIC SWITCH WHEREBY IN THE FIRST OR BPF POSITION OF SAID MODE SWITCH THE OUTPUT OF THE BAND PASS FILTERS OF SAID TELEMETRY RECEIVER ARE SEQUENTIALLY SCANNED BY SAID ELECTRONIC SWITCH AND IN THE SECOND OR DEFLECTOR POSITION OF SAID MODE SWITCH THE OUTPUT OF THE DETECTOR PORTION OF EACH OF SAID ELEMETRY CHANNELS ARE SEQUENTIALLY SCANNED BY SAID ELECTRONIC SWITCH;
