WebFor example, averaging 4 measurements, one can improve signal-to-noise ratio twice, averaging 100 measurement will reduce the noise level 10 times, and so on. One limiting factor in improving quality of the measurements by averaging is the time needed to repeat the measurements. WebThis is not possible. The input noise will be amplified just as much as the signal. Plus, some additional noise will be added by our amplifier. So the overall effect is the output SNR is lower than the input SNR. (This is why the NF is positive when expressed in dB) But we want the SNR to be reduced by as little as possible. Share Cite Follow
