Analysis of the meaning of common capacitors in different circuits(III)

13. Timing capacitance

A capacitor in series with a resistor R in RC timing circuit determines the time.

14. Buck current limiting capacitor

It is connected in series to the AC circuit to carry out partial voltage and current limiting for capacitance reactance of alternating current.

15. Shortening the capacitance

This capacitance is a capacitor that is concatenated in order to shorten the length of the oscillation inductor in the UHF tuner.

16,. KRA spilt capacitor

In the capacitor three point oscillating circuit, the capacitance of the oscillating inductance coil is connected in series, so as to enhance the frequency stability for the influence of the junction capacitance of the water transport transistor.

17. Scylla capacitor

In the capacitance three point oscillating circuit, and connected to the capacitance at both ends of the oscillating inductor coil, in order to eliminate the influence of the transistor junction capacitance, the more easy the oscillation frequency is, the easier it is to rise and vibration.

18. Acceleration capacitance

In the oscillatory feedback circuit, the positive feedback process is accelerated and the oscillation amplitude is increased.

19. Pre accentuation capacitor

In order to prevent attenuation or loss of high-frequency components during the modulation of audio modulating signals, the capacitance of RC network with high frequency components is appropriately promoted.

20.To increase the capacity of the capacitor

The part of the high frequency component which is pre - promoted in the audio signal is attenuated together with the noise, and the capacitance in the RC network of the original appearance of the sound signal is resumed.

21. Stable amplitude capacitance

In a frequency discriminator, it is used to stabilize the amplitude of the output signal.
