It is well known that averaging N independently noisy versions of an otherwise constant signal, x, reduces the rms value of the noise by a factor of radicN, regardless of the distribution of the noise. However, this result applies exactly only if each noisy version of the signal can be added together with infinite precision. If averaging is performed after digitisation, the nonlinearity imposed by quantisation affects the performance of the averaging. For the case of averaging after a coarse… CONTINUE READING
