ABSTRACT:
A high-resolution digital filter including a memory structure receiving as input a sampled digital signal, and an adder chain with delay blocks connected between the adder chain and the memory structure. The adders are connected to memory outputs to convert the input signal into an output signal having predetermined frequency response characteristics. The memory structure includes at least one pair of non-volatile memory elements, each memory element being input one portion only of the sampled signal.
