摘要：
The output frequency response for most DACs rolls off according to the sin(x)/x frequency-response envelope [1]. This paper derives a FIR filter which is designed in the minimax sense with the ripple constraints as the design criteria for the frequency response compensation of DACs. The filter order estimation function under the criterion gives a detailed filter design configuration method, which can effectively shorten the design time and provide an accurate resource configuration reference for the top-level system design [2]. The simulation example verifies the advantages of the compensation filter in minimax sense and shows the performance of the compensation filter and the accuracy of the order estimation function.
