A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
Advantages:Even a small value of input voltage can be amplified using instrumentation amplifier.Disadvantages:For transmission purpose for long range, noise also gets superimposed along the original wave. Therefore specific cables are used to reduce noise.
aei's are applied electronics and instrumentation engineers these are related to instrumentation field. the main purpose is to in measurement and controlling
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
To bias the transistors at 0.7 Volts.
The purpose of impedance matching is to provide for the highest efficiency between either the stages of an amplifier circuit or from a device to the amplifier for the same purpose. Impedance matching us used to make the circuits compatible based on electrical characteristics of a particular circuit from one section (or stage) to the next.
Instrumentation and control engineering is very useful to control processes in different industries.Temperature control,steam flow control and level control are some common examples of control engineering....
Finding a sense of purpose in the story.
To increase the signal-to-noise ratio of an audio signal prior to input into the main amplifier. The SNR is generally increased using a differential amplifier. Oftentimes this is unnecessary, and the purpose of the preamplifier is to increase the signal voltage prior to amplifying the current in the power amplifier stage.
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
