  • Page 24 BR200D-U1/BR300D-U1 Service Manual Figure 3 Schematic Diagram for IF System Receiving Audio Signal Processing: The audio processing circuit of receiver consists of IC300. Voice signals from IC300 are sent to IC301 （CTCSS signaling filter circuit. Squelch Circuit Part of the AF signal from the IC200 enters the FM IC again,and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.
  • Page 25 BR200D-U1/BR300D-U1 Service Manual The audio signals after demodulation in IC200 may contain CTCSS (continuous tone control squelch system) or DCS（digital squelch）signals. The spectrum component of CTCSS/DCS is 67 to 250Hz. The filtering circuit composed of IC301 can filter out signals except CTCSS/DCS spectrum, which makes MCU decode the CTCSS/DCS more accurately.
