Why study radio？The radio is the sparrow of electronic products. Although it is small, it has all the internal organs.Mastering it in the right sense will e a qualitative leap in your electronic level. In order to exercise hands-on ability and improve welding technology, the radio circuit includes high-frequency amplifier, intermediate frequency amplifier, audio voltage and power amplifier, frequency conversion circuit, tuning circuit, automatic sine wave oscillation circuit, circuit, automatic gain control circuit, volume control It is an indispensable functional circuit in many electronic circuits such as circuits. Learning radio can lay a solid foundation for you to learn the working prince and maintenance of other electronic circuits in the future.
