the purpose of attenuator is to​

Answer 1

Answer:

Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it.

Answer 2

An Attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform .

Explanation:

1. An Attenuator is effectively the opposite of an amplifier , though the two work by different methods .
2. Attenuation is the loss of signal strength in networking cables or connections .
3. Attenuators are also used to match impedance apparent SWR (Standing Wave Ratio) .
4. They are usually passive devices made for simple voltage divide networks .
5. Switching between different resistances form adjustable stepped attenuators and continuously adjustable ones using potentiometers .
