Attenuator (electronics)
Construction and UsageAttenuator CircuitsAudio AttenuatorsComponent Values For Resistive Pads and AttenuatorsSee AlsoReferencesExternal LinksAttenuators are usually passive devices made from simple voltage divider networks. Switching between different resistances forms adjustable stepped attenuators and continuously adjustable ones using potentiometers. For higher frequencies precisely matched low VSWR resistancenetworks are used. Fixed attenuators in circuits are used to lower voltage,...See more on en.wikipedia Google Patents
