WebMay 18, 2024 · It seems the signal power is 3dB higher than actual power. Does anyone can explain me why? For example, I have f (t)=A*sin (2*pi*f*t), its power is f (t)^2 integrated over a cycle then divide the cycle period, (1/T*int (f (t)^2)) which is equal to A^2/2 as expected. (match with RMS calculation as well = (A/sqrt (2))^2) WebJan 12, 2013 · The noise is then estimated by subtracting the signal estimate from the noisy measurement. The ratio of the power of the two estimates yields an estimate of the SNR. If the noise is multiplicative, the logarithm of the square of the measurement is used. Hope this helps.
