摘要： The digital filter includes a plurality of parallel adders, each whereof has a first input, a second input and an output; the parallel output of each adder is connected to the first input of the successive adder across a respective delay element. The second input of each adder is connected in parallel to the output of one of a plurality of memory banks, each whereof comprises a plurality of addressable memory cells, the addressing inputs whereof can be driven by a sampled digital signal to be filtered, and the memory cells of each bank contain a digital value which is equal to the product of a preset coefficient by the address of the cell itself.
