Sign Data Derivative Recovery [PDF]

ISRN Applied Mathematics, 2012
Given only the signs of signal plus noise added repetitively or sign data, signal amplitudes can be recovered with minimal variance. However, discrete derivatives of the signal are recovered from sign data with a variance which approaches infinity with decreasing step size and increasing order.
