Summary

AK2347, in addition voice filter, limiter, to splatter filter, emphasis, compander, scrambler circuit,

Has a built-in programmable LPF for CTCSS, is an IC with a single chip the baseband section of the radio. HPF of the audio filter, reliable sub-audio signals, such as CTCSS shows a high attenuation rate below 250Hz To achieve the removal. Also limiter circuit, it is possible to adjust the limit level by connecting a resistance to external.
