What Is Attenuation?

1.	What Is Attenuation?
Answer» Attenuation is the reduction in amplitude and intensity of a signal. Signals may ATTENUATE exponentially by transmission through a medium, or by increments calculated in electronic CIRCUITRY or set by variable controls. Attenuation is an IMPORTANT property in telecommunications and ultrasound applications because of its IMPORTANCE in determining signal strength as a function of distance. Attenuation is usually measured in UNITS of decibels per unit length of medium (dB/cm, dB/km, etc) and is represented by the attenuation coefficient of the medium in question.
