Beschreibung
The FM/AM tuner developed aiming at the syntony precision which was excellent in the synthesizer scheme, and the tone quality and receiving performance exceeding an analog method.
Hyena G, PLL, and the circuit are adopted, a large loop gain is taken from the conventional PLL, and the speed of response is improved by about 3 times by high power-ization and high-speed-izing.
Moreover, the large improvement in error revise capacity is realized by giving a margin to the syntony voltage of a varactor diode etc. so that it can follow in footsteps of accelerated PLL.
Furthermore, with an implementation of a fast turn-around, the comparison frequency which was 12.5kHz conventionally could be set as 25kHz outside an audio frequency band, and the component has eliminated the problem which has an ill effect to an audio signal system.
