SpletThis approach provides a straightforward conceptual framework in which RF circuits are fundamentally a means of transforming a lower-frequency information signal into a higher-frequency transmitted signal, or a higher-frequency received signal into a lower-frequency information signal. SpletA crystal oscillator relies on the slight change in shape of a quartz crystal under an electric field, a property known as inverse piezoelectricity. A voltage applied to the electrodeson the crystal causes it to change shape; when the voltage is removed, the crystal generates a small voltage as it elastically returns to its original shape.
