elch circuit and audio output; it also specifically sets search tuning circuit, signal detection circuit and frequency locked loop. It can use a varactor diode to replace the variable capacitor is, which is a special kind of diodes. The PN junction capacitance is changed with the bias voltage ( reverse voltage) on PN junction.
