What are the applications of hartley oscillator?
hartley oscillators are mainly used in radio receivers. Also note that due to its wide range of frequencies it is the most popular oscilator
How does the intelligence signal modulates the carrier?
There are three major types of modulation:AM, Amplitude Modulation, where the modulation signal is altering the amplitude of the carrier according to its own amplitude, normally this is done in the output stage. Therefor a strong audio signal is necessary at the same or a little less than the power of the carrier, never higher, because that will over modulate the carrier that will resort in distortion of the receiver output. AM is used in the lower band of the RF spectrum.FM, Frequency Modulation, where the frequency of the carrier is altered by the audio signal. When the amplitude of the audio is going higher the frequency go lower. Modulation happen at the oscillator stage, therefor a small audio signal is used to modulate the frequency. FM is normally used in the higher frequency range of the RF spectrum, 50MHz and up.FSK, Frequency-shift keying, used for data transmission, this type of modulation is simply, switching the carrier on and of, a high bit will switch the oscillator on and a low bit will switch it off, in some designs a low will be on and a high off.
Which type of modulation is used in TV transmission?
In television system for video transmission AM is used and for audio transmission FM is used....
What is voltage sweep generator?
A: Sometimes a spectrum of frequency must be analyzed a voltage to frequency converter can be used to sweep a range of frequency just by changing some DC level.
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
What is the main use of frequency modulation?
Frequency modulation is used to broadcast radio waves to receivers. The most common use of it is in FM radio, which contains a range of radio frequencies.
Where use 30hz to 30khz frequency?
The 30 Hz to 30 kHz frequency range is commonly used in audio applications. It covers the audible frequency spectrum for humans, making it suitable for music, speech, and sound reproduction in speakers and headphones. It is also used in various electronic devices such as microphones, amplifiers, and audio processors.
What are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
What are AV receivers and where can I find out this information?
Av receivers from my understanding stand for audio video receivers and are used in home theater systems they're used to amplify sound from different audio sources and also send video to your TV from other sources. A simple way to find out more on AVA receivers would be to go to you local electronic store and ask a member off staff for more information.

What is the loudspeaker used to produce high frequency sound called?
The loudspeaker used to produce high frequency sound is called a tweeter. Tweeters are designed to reproduce frequencies in the higher range of the audio spectrum, typically above 2,000 Hz. They are commonly used in audio systems to enhance the clarity and detail of sound reproduction.
What is the components of intermediate frequency amplifier?
Commonly used intermediate frequencies110 kHz was used in Long wavebroadcast receivers. [1]Analoguetelevision receivers using system M: 41.25 MHz (audio) and 45.75 MHz (video). Note, the channel is flipped over in the conversion process in anintercarriersystem, so the audio IF frequency is lower than the video IF frequency. Also, there is no audio local oscillator, the injected video carrier serves that purpose.Analoguetelevision receivers using system B and similar systems: 33.4 MHz. for aural and 38.9 MHz. for visual signal. (The discussion about the frequency conversion is the same as in system M)FM radioreceivers: 262 kHz, 455 kHz, 1.6 MHz, 5.5 MHz, 10.7 MHz, 10.8 MHz, 11.2 MHz, 11.7 MHz, 11.8 MHz, 21.4 MHz, 75 MHz and 98 MHz. In double-conversion superheterodyne receivers, a first intermediate frequency of 10.7 MHz is often used, followed by a second intermediate frequency of 470 kHz. There are triple conversion designs used in police scanner receivers, high-end communications receivers, and many point-to-point microwave systems.AM radioreceivers: 450 kHz, 455 kHz, 460 kHz, 465 kHz, 470 kHz, 475 kHz, 480 kHzSatellite uplink-downlinkequipment: 70 MHz, 950-1450 Downlink first IFTerrestrial microwaveequipment: 250 MHz, 70 MHz or 75 MHzRadar: 30 MHzRF Test Equipment: 310.7 MHz, 160 MHz, 21.4 MHz
What sound is in the 6K hz range?
A sound in the 6 kHz range would be in the higher frequency range of human hearing. It is typically described as a high-pitched tone similar to a squeal or whine. This frequency range is commonly used in audio equipment testing and calibration.
What are the different ranges of the frequency spectrum?
The frequency spectrum is typically divided into different ranges: Audio frequency range: 20 Hz to 20 kHz, encompassing frequencies audible to humans. Radio frequency range: typically ranges from a few kHz to several GHz, used for communication and broadcasting. Microwave frequency range: typically ranges from several GHz to a few hundred GHz, used in microwave ovens and telecommunications. Infrared and visible light range: above microwaves, including the spectrum of visible light and beyond. Ultraviolet, X-ray, and gamma-ray range: higher frequencies with increasing levels of energy and potential harm.
What is 20 kHz?
20 kHz refers to a frequency of 20,000 hertz, which is in the range of human hearing. It is commonly used in audio equipment specifications and is at the upper limit of what most people can hear.
What is the telephone frequency range used for communication?
The telephone frequency range used for communication typically falls between 300 Hz to 3.4 kHz.
What is the use of a car?
Car receivers are typically used in vehicles to pick up radio stations outside of the local range. These receivers can also be converted for home use.
