摘要：A necessary number of initial stage element circuits (2), intermediate stageelement circuits (1), and final stage element circuits (3) are connected in cascade andcombined in parallel arrangement simultaneously. The artial sum output data (8) on theelement circuits is synchronized with the inner partial sum data. In this way, it is possibleto configure a high-speed high-order and high-precision FIR filter, i.e., a large-scale digitalfilter. Thus, it is possible to manufacture a high-order and high-precision FIR filter capableof high-speed operation of 2 GHz or above at a low cost.
