What is the purpose of resonance circuit?
Resonance describes a 'condition' rather than a 'purpose', but it is made use of in (for example) radio circuits, in order to tune the radio to a particular frequency (the resonant frequency of the signal).
What is intermediate frequency?
In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier frequency is shifted as an intermediate step in transmission or reception. [1] The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process calledheterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequencies are used in superheterodyne radio receivers, in which an incoming signal is shifted to an IF for amplification before final detection is done. The intermediate frequency stays the same for all signals, for example 455 kHz in an AM broadcast receiver.Conversion to an intermediate frequency is useful for several reasons. When several stages of filters are used, they can all be set to a fixed frequency, which makes them easier to build and to tune. Lower frequency transistors generally have higher gains so fewer stages are required. It's easier to make sharply selective filters at lower fixed frequencies.
What is the practical use of astable multivibrator?
it can be used any where, where we need the clock pulse train of low frequancy.like a function generator contains.astable multivibrator is used to produce waveformsas Astable means the circuit is not set to one state or the other but rather oscillates between those states. Therefore the application is signal generation
How are capacitors used in speaker applications?
Capacitors are used to limit the frequencies sent to speaker units in multiple speaker applications. As the frequency increases, so does the effective resistance of the capaitor. (known as reactance) For instance, tweeters only work efficiently with high frequencies. Applying low frequencies to these devices is inefficient and could cause harm to the unit. Putting a capaitor in line with it will only allow high frequencies through. Using a combination of capacitors and coils, in parrallel to form filters, can make only desired frequencies pass to the correct driver unit. Each speaker can then work most effeciently with the desired frequency. This is a fine art, to make sure that the sound is pure and not coloured or distorted and has to also match the cabinet in which the drivers are mounted.
What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier signal.
What would you be using if you were trying to tune into an AM or FM frequency?
You would be using a radio if you were trying to tune into an AM or FM frequency.

What would l be using if I was trying to tune into an AM or FM frequency?
You would probably be using a radio receiver. It is possible you'd be using a transceiver, which combines the functions of a transmitter and a receiver.

a radio
How do you change the frequency of a guitar?
To change the frequency of a guitar string, you would adjust the tension on the string by turning the tuning pegs. Tightening the string increases the frequency, while loosening it decreases the frequency. Tune the string to the desired pitch using a guitar tuner or by ear.
What should the beat frequency of two in-tune instruments be?
The beat frequency of two in-tune musical instruments is zero.
What CD does the REM tune of What is the Frequency Kennith appear?
The tune of What's the Frequency Kennith appears on REM's Monster cd. The song was written by Bill Berry.
How do you manually tune seat ibiza radio?
To manually tune the radio in a Seat Ibiza, first, turn on the car's audio system. Then, press the "Radio" button to access the radio mode. Use the "Tune" or "Seek" buttons to adjust the frequency up or down until you find your desired station. Alternatively, you can enter the frequency directly using the number keys if your model allows it.
