WebMay 22, 2024 · 1.3.3 Decibels. RF signal levels are expressed in terms of the power of a signal. While power can be expressed in absolute terms, e.g. watts ( W ), it is more useful to use a logarithmic scale. The ratio of two power levels P and PREF in bels ( B) is. P(B) = log( P PREF) where PREF is a reference power. Here logx is the same as log10x. WebThe frequency of a waveform is the number of times a complete waveform is repeated in a fixed time period.
