FM demodulation circuit using TA7343

Currently used stereo decoders, due to the manufacturing process of the integrated circuit itself, can ensure a separation of more than 45 dB between the two channels, as long as
the intermediate frequency amplification gain is high enough. It is easy to achieve signal channel separation greater than 20 dB, so the separation generally does not have an adjustment circuit. However, the currently
commonly used TA7323P decoder should adjust the free oscillation frequency to ensure the best stereo separation.
