Jabarkan Parangkat nu patali dari Dioda dalam bahasa sunda

Thyristor atawa silicon controlled rectifier (SCR)

The first use for the diode was the demodulation of amplitude modulated (AM) radio broadcasts. The history of this discovery is tréated in depth in the radio article. In summary, an AM signal consists of alternating positive and negative péaks of voltage, whose amplitude or 'envelope' is proportional to the original audio signal, but whose average value is zero. The diode (originally a crystal diode) rectifies the AM signal, léaving a signal whose average amplitude is the desired audio signal. The average value is extracted using a simple filter and fed into an audio transducer, which generates sound.
