The exciter is really a very small transmitter. It produces the exact kind of signal that the transmitter makes, except that its power is too low to be of much use. In the transmitter there is an amplifier that boosts this low power to a high level so that it can reach farther.
A classical design example is an FM transmitter. A small exciter cabinet contains an audio input section, and RF oscillator and modulator, and a small power amplifier of perhaps 10 watts, and a small power supply to run these things. This is the exciter. The audio feed is sent into the exciter and an FM signal comes out. If you were close to the exciter with your receiver, and the exciter were connected directly to the radio antenna, you could listen to the station just fine.
But 10 watts will only go a few miles. To cover a small town, you might need 1000 to 10,000 watts, or for a large city, you could use 100,000 watts.
The transmitter therefore includes, besides the exciter cabinet, a much larger cabinet, or set of cabinets, containing a substantial power supply and amplifier to boost the exciter's power output to the proper level. It is this high-power output that is fed to the antenna.
What else can I help you with?
What is the function of exciter rotor and stator in Generator Operation?
In the operation of a standard generator, the exciter rotor and stator provide DC-type energy to an AC-type supply. This allows the exciter to maintain a constant DC source.
What are the function of transmitter?
function of transmitter:-1. generate a signal of desired correct transmitting frequency2. modulation3. power amplification
Do generators have brushes?
Most do, but not all. Some have a separate exciter winding.
What is the most powerful transmitter of culture?
Language is the most powerful transmitter of culture.
How do you calibrate displacer type level transmitter?
You have to specify which type of calibration you want to perform on the transmitter dry, wet or online calibration ?
What is a exciter used for and why?
exciter is a component in a electrical generator and or the low power rf stages of a radio transmitter
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.
What is the function of exciter rotor and stator in Generator Operation?
In the operation of a standard generator, the exciter rotor and stator provide DC-type energy to an AC-type supply. This allows the exciter to maintain a constant DC source.
What are the function of transmitter?
function of transmitter:-1. generate a signal of desired correct transmitting frequency2. modulation3. power amplification
What is the function of dehydrator in an FM transmitter?
to transmit signals
What different rotary exciter and static exciter?
Static exciter mounts as part of the motor control package, separate from the motor. Rotor exciter mounts on the rotor of the motor.
What is the main function of the scosche fm transmitter?
The main function of the scosche fm transmitter is to encrypt signals so that you're not accidentally encroaching on another random person's transmissions.
When was Exciter - band - created?
Exciter - band - was created in 1978.
When was Exciter - album - created?
Exciter - album - was created in 2000-06.
How do you connect and test exciter voltage?
To start the ac motor at starting by exciter.
When was Impact Exciter created?
Impact Exciter was created on 2010-07-07.
What is the function of the amplifier in a transmitter?
used to increase the power level of the transmitting signal
