WebSummary: Attenuators. An attenuator reduces an input signal to a lower level. The amount of attenuation is specified in decibels (dB). Decibel values are additive for cascaded attenuator sections. dB from power ratio: dB = 10 log10(PI / PO) dB from voltage ratio: dB = 20 log10(VI / VO) T and Π section attenuators are the most common circuit ...
