What component of an AM transmitter generates the carrier frequency?
The classic AM transmitter layout is a master oscillator, followed by a "pen", or penultimate amplifier, followed by a PA or power amplifier. The master oscillator, which is probably crystal controlled, generates the carrier frequency.
The function of an oscillator in a radio transmitter is to?
There are typically at least two oscillators involved in the transmission aspect of a radio transceiver: one is the transmission oscillator which creates a cosine waveform modified with the input key (the information being broadcasted), the other is the variable frequency oscillator which allows one to select the desired frequency for communication. On most transceivers the VFO also modifies the receiving end of the device simultaneously.
What is Wireless transmission system?
A wireless transmission consists of at a minimum: input signal (the data or analog signal you wish to transmit), transmitter, 2 antennas, space (the final frontier) and a receiver/reproducer. This only makes one way transmission possible. You would need an additional: transmitter, receiver/reproducer and 2 antenna couplers (allows both a transmitter and receiver to use the same antenna) to have 2 way communication. A basic transmitter consists of a power source, a signal generator (oscillator), signal converter/amplifier, mixer (mixes the oscillator and amp signals to create the transmitted signal), output amplifier. a receiver is similar to a transmitter except instead of mixing the signal with the oscillator signal it removes the oscillator signal. Systems can be much more complicated depending on power needs (distance between antennas, frequency interference...) and application (encoder/decoder, security or digital conversion).
What type of oscillator has got frequency stability?
A: desirable oscillator will have no frequency deviation as a function of external influences such as temperature and more. Stability is measured as a % factor considering outside interferences
What is the final stage of a transmitter in telecommunication?
The power amplifier that drives the antenna. In CW transmitters and some AM transmitters this stage is also the modulator, in others (and in non-AM transmitters) the modulator is in an earlier stage.
What are the component of transmitter?
Power supply, oscillator, modulator, and amplifier.
How do you convert DC to AC in an oscillator?
that is the function of the oscillator

Why is a crystal oscillator required in a radio transmitter?
SOME kind of oscillator is required, to create the AC signal that will be modulated, amplified, and eventually sent up to the antenna to be transmitted. It doesn't have to be a crystal oscillator, though.
What is the basic function of tuning capacitors?
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.

Why oscillator is needed in transmitter circuit?
Low frequency signal are not able to get propagated throught longer distance. So it is to be carried by a carrier wave. Hence high frequency carrier wave is to be generated by the help of an oscillator. So we need an oscillator here a crystal oscillator to produce high frequency carrier waves.
What are the function of transmitter?
function of transmitter:-1. generate a signal of desired correct transmitting frequency2. modulation3. power amplification
What is the Frequency of cw channel?
the problem is there is a transmitter called CW, which means whenever i Google it i find all pages talking about the transmitter , the only way to know that is by talking to someone who is American and I'll give it a try and if i'v got something I'll let u know ... just keep in touch
Wave function for time independent harmonic oscillator?
The wave function for a time-independent harmonic oscillator can be expressed in terms of Hermite polynomials and Gaussian functions. It takes the form of the product of a Gaussian function and a Hermite polynomial, and describes the probability amplitude for finding the oscillator in a particular state. The solutions to the Schrödinger equation for the harmonic oscillator exhibit quantized energy levels, known as energy eigenstates.
Cw radar vs cw radar?
CW in reference to radar usually means Continuous Wave. (CW Radar = Continuous Wave Radar) I don't think that it is usually referred to in a case sensitive way. You will need to explain the context better. Continuous Wave Radar references a radar system in which the transmitter is never turned off. The target illuminating, radio frequency emitter power is non-stop and unbroken. Isolation between the transmitter and receiver has to be specially considered during design.
