Measure frequency responce over the frequency range from 100Hz to 20,000Hz. The audio frequency response curve is shown in EXHIBIT # 9. (b) Modulation Limiting 2.1049 (c) Occupied_bandwidth: Using TIA/EIA 2.2.10 Accoustic Microphone Sensitivity test procedure to determine if the UUT could be put into modulation limiting and limiting could not be reached, the maximum deviation was only +40KHz. Using this test procedure the frequency of maximum sensitivity was determined to be 500Hz. a.
