摘要：

The design of discrete time differentiating filters, in the presence of colored noise and nonneglectable transducer dynamics, is investigated. The signal and noise are described by ARMA models, possibly with poles on \z\ = 1. The MSE optimal filter, based on a discrete time approximation of the derivative operator, is given by a spectral factorization and a linear polynomial equation.
