Signal power formula

WebThe formulae are as follows: Signal Power (dB) =10log_ {10} (\frac {Signal Power} {Reference Power}) Signal Amplitude (dB) =20log_ {10} (\frac {Signal Amplitude} {Reference Amplitude}) Note that in electronic communications, amplitude is usually in V RMS. The most important thing to notice here is that the dB scale is not an absolute scale. WebConsider the following equation of amplitude modulated wave. s ( t) = A c cos ( 2 π f c t) + A c μ 2 cos [ 2 π ( f c + f m) t] + A c μ 2 cos [ 2 π ( f c − f m) t] Power of AM wave is equal to the sum of powers of carrier, upper sideband, and lower sideband frequency components. v r m s is the rms value of cos signal.
