What is the purpose of a discriminator in an FM broadcast receiver?

The discriminator, and the ratio detector, perform the same function in an f.m. receiver as the detector does in an a.m. receiver, i.e. it recovers the modulation.

What is the purpose of an AF power amplifier in a FM broadcast receiver?
After FM demodulation to the original AF signal it is necessary to amplify the weak AF signal to have enough power to drive speakers. That is the purpose.
FM signals travel as what changes?
FM signals travel as changes in the frequency of the wave.ANSWER: DEFINITELY not frequency remains the same.The duty cycle changes.It definitely IS the the frequency which changes. It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator. If the frequency remained constant and its "duty cycle" changed, the discriminator wouldn't demodulate it.
Where does the radio station Maxima FM broadcast from?
The radio station Maxima FM broadcasts from South America, in Argentina. Maxima FM is broadcast directly from the city of Venado Tuerto, in north-east Argentina.
Full form of FM?
FM broadcasting is a broadcast technology invented by Edwin Armstrong that used Frequency Modulation (FM) to provide high fidelity sound over broadcast radio
What frequency swing is defined as 100 percent modulation for an FM broadcast station?
+-75kHz for FM broadcast. Not in general though. But it looks like you are looking for the answer to question 17 in modern electronics....+-75Khz will do
What is the purpose of limiter stage in a FM broadcast receiver?
It is to reduce interference form impulsive noise and even a.m. transmissions. If the receiver uses a ratio detector instead of the normal frequency discriminator it will be self limiting, thus eliminating the need for a separate stage.
What is the purpose of a Limiter in an FM broadcast receiver?
To minimize the interference form impulsive noise as well as the AM transmissions.
What is the purpose of an AF power amplifier in a FM broadcast receiver?
After FM demodulation to the original AF signal it is necessary to amplify the weak AF signal to have enough power to drive speakers. That is the purpose.
What is the need for limiter in FM receiver?
The limiter clips the top and bottom of the FM signal to remove any AM signal or static that was picked up. This prevents the FM discriminator from seeing those unwanted signals and inadvertently converting them to audio, scrambling the intended audio signal. Simply put, the limiter blocks interference and static making FM reception very clean.
When was Niigata Kenmin FM Broadcast created?
Niigata Kenmin FM Broadcast was created on 2000-12-20.
What is the broadcast band of Metro FM Lagos nigeria?
97.6 Fm

What are the types of FM receiver?
TYPES OF RADIO RECEIVER • Basic crystal set. • A T.R.F. Receiver. • A Superhetrodyne Receiver. • the Reflex Receiver.

What is the maximum modulating frequency in broadcast FM?
75khz
Foster-seely of FM demodulation?
Just like a diode demodulator extracts audio from the last IF stage in an AM radio, a Foster Seely or similar discriminator circuit extracts or demodulates audio from the last IF stage in a FM radio.
