摘要：
Three different designs are represented to compensate the sinc(x) frequency response distortion resulting from D/A converters, by using digital FIR filters. The filters are designed to compensate the signal's second image distortion. All filters are designed on a programmable logic device (PLD). The numbers of logic elements (LEs) needed in three different implementations are compared. The measured wideband code division multiple access (WCDMA) signal's second image meets adjacent channel leakage power specifications.
