Electronically Tuned Radio
Front End
front–end for the second generation MC13022 C–QUAM AM stereo IF and
decoder. The MC13025 provides a high dynamic range mixer, voltage
controlled oscillator, and first IF that with the MC13022 and synthesizer form
a complete digitally controlled AM stereo tuner system. This system in turn
may drive a dual channel audio processor and high power amplifiers for car
radio or home stereo applications. Other applications include portable radio
“boom boxes”, table radios and component stereo systems.
