Delta carrier levels are typically expressed in dBmV (decibels millivolts) in Cable Television and telecommunications systems. This unit of measurement provides a logarithmic representation of the change in signal levels between carriers, making it easier to analyze and troubleshoot signal quality and noise levels in the system.
5 mv is 14 dbmv.
dBmv is defined as 20 log (V/1mV) where V is the voltage converted into dBmv if X = 20 log (V/1mV) then V= (1/20) Antilog (X)
