APAKAH MAKSUD AUTOMATIC FREQUENCY CONTROL dalam CORSICA?

Kawalan frekuensi automatik

Automatic frequency control

Dalam peralatan radio, Kawalan Frekuensi Automatik, juga dikenali sebagai Penalaan Halus Automatik, adalah kaedah atau litar untuk memastikan litar resonant secara automatik ditala kepada kekerapan isyarat radio masuk. Ia digunakan terutamanya dalam penerima radio untuk memastikan penerima disetel kepada frekuensi stesen yang dikehendaki. Dalam komunikasi radio, AFC diperlukan kerana, selepas frekuensi bandpass penerima disesuaikan dengan kekerapan pemancar, kedua frekuensi mungkin akan terputus, mengganggu penerimaan. Ini boleh disebabkan oleh frekuensi pemancar yang kurang terkawal, tetapi penyebab yang paling biasa adalah melayang frekuensi jalur tengah penerima, disebabkan oleh aliran haba atau mekanikal dalam nilai-nilai komponen elektronik. Dengan mengandaikan bahawa penerima hampir disesuaikan dengan kekerapan yang dikehendaki, litar AFC dalam penerima akan menghasilkan voltan ralat berkadar dengan tahap yang mana penerima menerima mistun. Voltan ralat ini kemudian diberi makan kembali ke litar penalaan sedemikian rupa sehingga kesilapan penalaan dikurangkan. Dalam kebanyakan pengesan modulasi kekerapan, voltan ralat jenis ini mudah didapati. Lihat maklum balas negatif.

In radio equipment, Automatic Frequency Control, also called Automatic Fine Tuning, is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal. It is primarily used in radio receivers to keep the receiver tuned to the frequency of the desired station. In radio communication, AFC is needed because, after the bandpass frequency of a receiver is tuned to the frequency of a transmitter, the two frequencies may drift apart, interrupting the reception. This can be caused by a poorly controlled transmitter frequency, but the most common cause is drift of the center bandpass frequency of the receiver, due to thermal or mechanical drift in the values of the electronic components. Assuming that a receiver is nearly tuned to the desired frequency, the AFC circuit in the receiver develops an error voltage proportional to the degree to which the receiver is mistuned. This error voltage is then fed back to the tuning circuit in such a way that the tuning error is reduced. In most frequency modulation detectors, an error voltage of this type is easily available. See Negative feedback.
