The audio frequency response curve is shown on the next page. The audio signal was fed into a dummy microphone circuit and into the microphone connector. The input required to produce 30 percent modulation level was measured. SEE EXHIBIT 10. 2.987(b) 1 Audio input versus modulation The audio input level needed for a particular per- percentage of modulation was measured in accor- dance with TIA/EIA Specification 603. The audio input curves versus modulation are on the following pages. Curves are provided for audio input frequen- cies of 300, 1000, and 3000 Hz. SEE EXHIBITS 11A-11C. 95.635(b) Post Limiter Filter The filter must be between the modulation limiter and the modulated stage.
