resistor_attenuator_02 PUBLIC

Same as resistor_attenuator but edited to show how to measure the voltage across a floating component using a Voltage Controlled Voltage Source
(VCVS) with a gain (K) of 1.

An attenuator using resistors will usually have lower noise and better lineariity than some sort of voltage or digitally controlled attenuator. Depending on resistor tolerances, it may give a more accurate attenuation ratio than an active circuit. Resistors may be better at higher powers and higher

frequencies but excessive power dissipation in any attenuator can cause temperature related non- linearities and ultimately, damage. If variable attenuation is required then potentiometers or switched resistor arrays can
be used but if voltage or digital control is required then an electronically adjustable attenuator or variable gain amplifier is usually required.
