Where do we need attenuators?

[jo.thalbach]

Hi,

attenuators are said to be ubiquitous. Surely I have seen attenuators in oscilloscops and spectrum analyzers. What about other receivers? Are there attenuators in transmitters?

Yes receivers, like shortwave receivers, have G controls and some as well fixed value
attenuators. Transmitters control power by controlling the low level drivers with a
G control, eg. an attenuator of sorts.

A volume control is an attenuator.
My Sony Walkman radio has a Local-Distant switch on its FM signal input that is an attenuator because strong local stations overload the radio if the switch is set for Distant. Most radios have an automatic circuit that attenuates input signals that are too strong.
