To calculate attenuation for the DVC Digital Voice Command System DAA2 and DAX: Find the rated dB loss per foot within the cable manufacturer’s specifications. Determine the total attenuation between the two nodes due to the cable. Loss = (loss/ft.) x (length in feet). Model Fiber Type For direct fiber connection between (not used on this system).
The unit of attenuation is Decibels or d B and is 1/10th of a Bel that was developed by engineers at Bell Telephone Laboratories. A Decibel is a logarithmic unit that explains a relation of two measurements. The fundamental equation that explains the disparity in dB in between two measurements can be expressed as ΔX (dB) = 10log (X2/X1)
If V IN is the input voltage (or V S is the source voltage or V T is the transmitter voltage) and V OUT is the output voltage (or V D is the destination voltage or V R is the receiver voltage), then voltage attenuation is: Voltage Attenuation AV (dB) = 20 log10 | VIN / VOUT | Attenuation AV (dB) = 20 log10 | VS / VD |
