APPLICANT: J COMMUNICATIONS CO., LTD. FCC ID: OAJFR1500XTM REPORT #: T:\CUS\J\JCOM\298AK1\298ak1rpt.doc PAGE #: 2 2.1047(a)(b) Modulation characteristics: AUDIO FREQUENCY RESPONSE The audio frequency response was measured in ac- cordance with TIA/EIA Specification 603. 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 7. 2.1047(b) 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. Curves are provided for audio input frequencies of 300, 1000, and 3000 Hz. See Exhibit 8a-8c. 95.637(b) Post Limiter Filter The filter must be between the modulation limiter and the modulated stage. At any frequency between 3 & 20KHz the filter must have an attenuation of 60log (f/3) greater that the attenuation at 1KHz. See Exhibit 9. 2.9895c) EMISSION BANDWIDTH: 95.633(b)(1)(3)(7) Data in the plots shows that the sidebands from greater than 50% to 100% of the authorized bandwidth must be attenuated by at least 25dB and from 100% to 250% the sidebands must be attenuated by at least 35dB. Beyond 250% the sidebands must be attenuated by at least 43+log10(TP). The transmitter was modulated with 2500 Hz, and adjusted for 50% modulation plus 16 dB.The spectrum analyzer was set with the unmodulated carrier at the top of the s…
