Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.

What is the modulation of frequency?
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
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.
What is the frequency range used on all audio receivers?
The frequency range used on all modern audio receivers is 10.7 to 12.75 GHz. The IF range is 950 to 2150 MHz. Audio receivers are also known as radios.
What is the maximum frequency output can get from 555?
3MHz
What is iir filter's applications?
IIR filters have nonlinear phase characteristic which means the output of such a filter is (most likely) a deformed version of the input without the filtered frequency. On the other hand IIR filters might become unstable. So IIR filters are used, when the user is not particularly interested in the output in time-domain but only in frequency-domain, e.g. in audio applications such as speakers...
Why the output of the envelope detector changed frequency when the audio frequency was varied?
answer for me please
What is an audio frequency?
An audio frequency is a frequency, or range of frequencies, of audible sound waves.
Does audio output device can output only music?
No, it can output any type of audio.
What is the definition of audio-frequency transformer?
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
In AM transmission the frequency which is not transmitted is?
audio frequency
What is AV stand for on a TV?
Audio and Visual output is visual and audio
How audio input Jack covert to audio output jack?
If I understand the question, you are trying to intertwine different functions. Like your ears, the audio input jack receives an audio source, while the audio output jack transmits outputs audio content - similar to your mouth. If you are trying to redirect the input audio directly to the audio output port you will need a "passthru" (aka monitor) function. -P2E
What type of output is VolP?
Audio
What is output frequency of bridge rectifier?
twice the input frequency
What is stereo audio input?
That would be where you connect anything with a STEREO AUDIO OUTPUT.
What type of output does head phones or speakers sendout of a computer?
Audio output.
How do op-amp amplify in signal conditioning?
If an inline capacitor is inserted in the feedback from the output to the input of an op-amp it will act as a frequency filter and only boost audio frequencies within the resonant frequency range of the capacitor. If you gang multiple op-amps in a wein bridge arrangement you get an analogue audio filter capable of shelf boost or cut.
