Attenuation decreases the intensity of electromagnetic radiation due to absorption or scattering of photons. Attenuation does not include the decrease in intensity due to inverse-square law geometric spreading. Therefore, calculation of the total change in intensity involves both the inverse-square law and an estimation of attenuation over the path. dewalt battery specialsWebSignal input -> attenuation circuit (reduce incoming signal level) -> op amp input (amplify signal level) sorry for late response.
