While an amplifier provides gain, boosts the signal, an attenuator provides loss, reduces the signal. Attenuators are always a compromise and should only be used if absolutely necessary.

Programmable attenuators and direct-read attenuators that can be set by an external device such as rotary dial are also available. With a digital attenuator, the attenuation can be varied by digital ...
