  • Abstract
    An analytic method for the compensation of the (sin x)/ x distortion inherent to digital or sampled-data systems with continuous-time output signals is presented. The compensation is achieved through the insertion of a pair of finite zeros in the transfer function of the system. Simple expressions are provided for the calculation of the magnitude and the Q-factor of the zeros of the compensation function. An example illustrates the efficiency and the applicability of the method. Simulation results are presented for a second-order Chebyshev filter
