Automatic Frequency Control (AFC) typically employs negative feedback to maintain a stable frequency in oscillators and receivers. This feedback works by comparing the output frequency with a reference frequency; any deviation results in adjustments to the oscillator's frequency to minimize the error. By continuously monitoring and correcting the frequency, AFC ensures that the output remains locked to the desired frequency, enhancing signal stability and performance.

What are the disadvantages of using automatic machining?
Automatic machinery; or cnc, can actually (and ironically) be less cost effective when it comes to one of a kind parts or some prototype work.
What kind of transformer whose purpose is to combine audio frequency signals with high frequency carrier signals in a radio transmitter?
The transformer used to combine audio frequency signals with high-frequency carrier signals in a radio transmitter is called a modulation transformer. This type of transformer effectively couples the low-frequency audio signals to the high-frequency RF (radio frequency) carrier, allowing for efficient transmission of the combined signals. It ensures minimal loss and maintains the integrity of both frequency components during the modulation process.
Mathematical expression for side band amplitudes in FM signal?
In frequency modulation (FM), the sideband amplitudes can be expressed using Bessel functions. For an FM signal with a modulation index ( \beta ) (the ratio of the frequency deviation to the modulation frequency), the amplitudes of the sidebands are given by ( J_n(\beta) ), where ( J_n ) is the Bessel function of the first kind of order ( n ). The sideband amplitudes corresponding to the carrier frequency will have values of ( J_n(\beta) ) for ( n = 0, \pm 1, \pm 2, \ldots ). Thus, the total signal can be represented as a sum of these sidebands, modulated around the carrier frequency.
What is DC drives?
A DC drive is a kind of equipment ordinarily do control a speed, tension and current on a Direct Current Motor (DC Motor), in order to have a certain process transformation under control.
What kind of feedback control does transparency show?
dont know the answer hahahah bi*h
How do you set radio to use linear?
Depends on what exciter (transmitter, or transmitter part of a transceiver) you are using and what kind of linear you will be using. Generally, the transmitter part is 100 watts or less out to your linear. This is the RF (Radio Frequency) connection. The other connection is ALC (Automatic Limiting Control). This is a feedback connection from your linear to your exciter which controls the exciter to decrease power. The ALC hopefully will prevent over driving the linear so your signal will not be distorted. There can be other control cable/s which allow your exciter to control the linear's band (frequency) setting. This is just basic information and one must compare the equipment manuals or ask the manufacture of your equipment for advice.
How does a signal generator work?
For ac usually is a non linear resistance that can be used to change frequency Or a relaxation oscillator can supply square waves and filter it to get the basic frequency.. piratically all of them needs some kind of positive feedback
Which kind of feedback is used to reinforce correct behavior?
constructive feedback
What kind of feedback mechanism is it when it causes the initial stimulus to decline?
negative feedback
What kind of feedback is used in emitter follower?
emitter follower is a type of negative feedback ,
What kind of feedback is required to keep internal conditions in the body constant?
Negative feedback.
Is this sentence grammatically correct It would be very kindly if you can leave a positive feedback?
it would be kind if you could leave a positive feedback Or, It would be kind of you to leave positive feedback. Perhaps better: I would be grateful if you leave your honest feedback.

Negative
What kind of automatic transmission fluids can go into a 1998 dodge neon?
Any of them if it is automatic.
What kind of feedback mechanism help maintain homeostasis causing a stimulus to increase?
YES, + feedback systems enhance or intensify the stimulus. Eg. of a + feedback system = childbirth
