  • Page 4: Transmitter System

    5. Squelch Circuit The detected output which is outputted from pin 9 of IC108 is inputted to pin 8 of 1C108 after it was been amplified IC120:A and it is outputted from pin 7 after the noise component was been eliminated from the composed band pass filter in the built in amplifier of the iC, then the signal is rectified by the internal diode in IC108 to convert into DC component.

  • Page 5: Cpu And Peripheral Circuit

    3. Phase Comparator Circuit The PLL (IC116) uses the reference frequency, 5 or 6.25 kHz. The phase comparator in the 10116 compares the phase of the frequency from the VCO with that of the comparison frequency, 5 or 6.25 kHz, which is obtained by the internal divider in IC116.

    7. CTCSS, DCS Decoder The voice band of the AF output signal from pin 1 of IC120:A is cut by sharp active filter IC104:A, B and C (VCVS) and amplified, then led to pin 4 of CPU. The input signal is compared with the programmed tone frequency code in the CPU.
