Walmart and Radioshack sell FM modulators. these are mostly used to send audio from a I- POD or other device to a FM car radio tuned to the frequency of the modulator, some are switchable to avoid the frequency of any local FM radio station. For use at home get a power supply to power it from a wall socket. Some are stereo and some are mono.

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.
What is FM transmitter and what are the different FM transmitters?
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
Why frequency modulation is superior to amplitude modulation?
FM provides noise immunity, whereas AM is easily affected by noise. With FM, the amplitude of the sound is converted into a shift in frequency. So the volume is limited by the bandwidth, but the frequency of the sound can vary as much as it likes, giving a higher fidelity sound. Spikes induced on the signal usually affect the amplitude of the signal. The amplitude of an FM signal is not used in the demodulation process and is therefore immune to spikes in the signal. AM was first used in radio because it is very easy to achieve using basic components. A single rectifier only, is needed to recover the audio. FM is quite a complicated process and could only be achieved once electronics had progressed.
How are sound engineers and audio engineers different?
Mixing is a part of audio engineering. Mixing occurs after the recording process and before the mastering process. Recording, mixing, and mastering engineers are all audio engineers because they all deal with audio.
How do you detect FM signal?
FM signals can be detected using a frequency discriminator or a phase-locked loop (PLL) demodulator. The frequency discriminator converts the frequency variations of the FM signal into amplitude variations, which can then be amplified and filtered to recover the original audio signal. In a PLL, the incoming FM signal is compared to a locally generated signal, allowing for the extraction of the original information by tracking the phase differences. Both methods enable effective retrieval of the modulating audio or data signal from the FM carrier.
How can a condenser microphone be used to generate FM?
A condenser microphone can generate frequency modulation (FM) by converting sound waves into electrical signals. When sound waves hit the microphone's diaphragm, it causes variations in capacitance, which translates into corresponding voltage changes. These voltage changes can then modulate a carrier frequency in an FM transmitter, effectively encoding the audio signal onto the carrier wave. This process allows the microphone to wirelessly transmit the sound in an FM format.
How are sound waves converted into radio waves?
Sound waves would not ordinarily be converted INTO radio waves.Sound Waves can be used to modulate the radio waves.The radio frequency of a typical FM station is around 100MHz.The audio is used to vary the FM frequency by the range of audio waves, perhaps 100 Hz up to 12 kHz. So the 100MHz signal varies from 100 MHz ± (100 to 12kHz)
How to modulate the pitch of a sound signal?
Modulating the pitch of a sound signal involves changing the frequency of the signal. This can be done using techniques such as frequency modulation (FM) or pitch shifting. These methods alter the pitch of the sound without changing its overall quality.
How does FM transmitter work?
An FM transmitter works by modulating a carrier wave's frequency in accordance with an audio signal. The audio input is converted into an electrical signal, which then alters the frequency of the carrier wave. This modulated wave is transmitted through an antenna, allowing it to be picked up by FM receivers within its range. The receivers demodulate the signal back into audio, enabling sound playback.
Why do radio stations use FM for high quality music?
FM is not used to broadcast high quality music. FM is how the broadcast is carried out on to the airwaves. The high quality sound comes from the stations transmitter, compression, and different equipment to give the audio a good, crystal clear sound. Hope this helps!
What does the hear aid do?
Hearing Aids are used to amplify and *modulate sound for a partially deaf person. *Modulate - to adjust the pitch, tone or volume of sound.
Why FM is preferred for audio signal transmission?
FM also known as frequency modulation is preferred because of the more concise ability to transfer quality sound at the expence of distance. Also FM is not as severely effected by weather as its lower frequency AM counterpart.
Why inTV broadcasting video signal is trancemitted in AM but audio signal is in FM?
AM was used for the video signal because components to transmit and receive the video signal (tubes, originally) were not available that could modulate the frequency fast enough for the amount of information required for a video signal. The VHF band, where most of television broadcasts resided until the the adoption of Digital Television (DTV) was also being used for FM audio broadcasts.
Explain the meining of modem?
Modem stands for MOdulate DEModulate it takes digital information from your computer and turns it into sound (the MOdulate portion) and turns sound into data (the DEMod part)
What characteristic of an audio tone determines the percentage of modulation of an FM broadcast transmitter?
Only the amplitude of the audio tone determines the percentage modulation of an FM transmitter
Are tv sound and picture sent through FM waves?
Picture is AM, sound is AM or FM
When was Liffey Sound FM created?
Liffey Sound FM was created in 2006-09.
