摘要：
The envelope constrained (EC) filtering problem is the minimization of the noise gain of the filter while satisfying the constraint that its noiseless response to a specified input lies within a prescribed envelope, Using a hybrid filter consisting of an A/D converter, an FPR filter, and a linear interpolator, the problem is posed as a functional inequality constrained optimization problem, A technique for solving this problem is proposed by approximating it with a conventional unconstrained optimization problem that is then solved by a descent direction-based algorithm.
