The "tuning capacitor" in a radio is involved in determining the frequency of an
oscillator somewhere in the radio. As that capacitance is varied, the frequency
of the oscillator changes.
If the radio device is a transmitter, then the frequency on which it's transmitting
changes.
If the device is a radio receiver, then the frequency of the internal "local oscillator"
determines the frequency that will be selected, out of everything coming down from
the antenna, and then processed, detected, amplified, and filtered, for your listening
pleasure.

The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
What is the function of input and output coupling capacitors CC1 and CC2?
We don't know much about the circuit these capacitors are in, but they are coupling capacitors. Coupling capacitors isolate DC between stages or circuits, and they couple AC between those circuits or stages. Only the signal gets in and goes out. The DC the stage operates on is isolated from stage to stage.
How are capacitors rated?
Capacitors are rated in Microfarads
What are some simple electronic devices that are used in electrical engineering?
Resistors, capacitors, inductors, transformers, diodes, transistors, integrated circuits, power sources are the basic building blocks.
What variable capacitor used for tuning radio?
In radios that aren't solid state, and use variable capacitors for tuning, the air-dielectric variable capacitor is the almost universal choice for radio frequency applications. More information on air variable capacitors is available at www.orenelliottproducts.com.
What is the function of pulses?
tuning
What is the function of equalizing pulses?
tuning
What the basic components of tansmitter?
The basic components of a transmitter are; transistors, capacitors, resistors, condenser, Inductor, and antenna.
What is the function of ukulele capo?
It is used to change the tuning of the ukulele.
What is the function of a capacitors shortly?
*to store charge. *to smooth out(reduce ripple on dc) a voltage
The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
Which diode is used in frequency tuning application?
The varactor diode is used in frequency tuning applications. Its effective capacitance is a function of the reverse bias voltage across it.
Function of dielectric in a capacitor?
