What is meant by a 3 stage FM transmitter?
There are 3 stages of an FM transmitter which allow you to transmit information over the FM band. These 3 stages need to be integrated into a single circuit to form what is known as a 3 stage FM transmitterA modulator circuit to add the information to be transmitted to the carrier wave produced by the oscillator. This is done by varying some aspect of the carrier wave. The information is provided to the transmitter either in the form of an audio signal, which represents sound, a video signal, or for data in the form of a binary digital signal. In an FM (frequency modulation) transmitter the frequency of the carrier is varied by the audio signal.Many other types of modulation are also used. In large transmitters the oscillator and modulator together are often referred to as the exciter. An RF power amplifier to increase the power of the signal, to increase the range of the radio waves.An impedance matching (antenna tuner) circuit to match the impedance of the transmitter to the impedance of the antenna (or the transmission line to the antenna), to transfer power efficiently to the antenna. If these impedances are not equal, it causes a condition called standing waves, in which the power is reflected back from the antenna toward the transmitter, wasting power and sometimes overheating the transmitter.
What is a integrated FM modulator?
It's basically a circuit that's integrated into a single package, or is integrated into the complete circuit as an individual unit. There are several parts used in building a discreet modulator circuit and although it's not that complicated, it's by far less expensive for a manufacturer to come up with an IC to do the job as a single unit.
What is a tank circuit used for?
A tank circuit is used on a radio transmitter. It is an electronic circuit that is used to tune a specific frequency. The tank is made up of two components, an inductor and a capacitor. The two components are connected in a parallel with each other. This is where the term "tank" comes from. Used in a radio transmitter, it is tuned for maximum RF (radio frequency) output on the frequency the transmitter is tuned to.
What are the wired systems wireless systems and fiber-optic cable systems terms for the transmitter and receiver pair?
In wired systems the transmitter-receiver pair is commonly referred to as a modem (modulator/demodulator); in wireless systems the terms transmitter and receiver continue to be used; and for fiber-optic cable systems the terms electrical-to-optical (E/O) and optical-to-electrical (O/E) interfaces are used to describe the transmitter-receiver pair

What is coroot lattice?
Coroot lattice is a type of lattice that is used in trellises. The pattern of coroot lattice resembles a checkerboard.
What does a vacuum modulator do?
A vacuum modulator is used to apply pressure to the throttle valve. The modulator senses the pressure from the manifold and increases when the engine is under a heavier load.
What is crowbar in television transmitter?
In the context of television transmitters, a crowbar is a protective circuit used to safeguard sensitive components from voltage spikes or surges. It typically consists of a thyristor or similar device that triggers to short-circuit the power supply when an over-voltage condition is detected, thereby preventing damage to the transmitter. This mechanism helps ensure the reliability and longevity of the broadcasting equipment.
What type of radio transmitter was used on the ship Titanic?
The Titanic used a Marconi designed spark transmitter.
Could incandescent light be used for a fiber optic transmitter?
Incandescent light cannot be used for a fiber optic transmitter. This is because incandescent light is too slow for such a transmitter.
Can some antennas be used satisfactorily for transmission as well as for reception?
Yes, but you would need to remove the transformer that is used to match the antenna to the coax cable. This transformer will consume much of the transmitter power if left in the circuit.
Why power amplifier used in FM transmitter?
Amplifier is used in an FM transmitter to increase the level of a signal suitable for transmission
