Abstract: PURPOSE: To obtain the high-resolution digital filter which can occupy a single small silicon space in an integrated circuit and greatly save the time of manufacturing and filter programming stages. CONSTITUTION: The high-resolution digital filter includes memory structures 3 and 4 which receive a sampled digital signal as an input signal and an adder chain 13 which has a delay block connected between the memory structures and adders 10 and 11. The adders 10 and 11 are connected to the output sides of the memory structures and convert the input signal into an output signal having specific frequency response characteristics. The memory structures include a couple of volatile memory elements, which input only part of the sample siganl.

Abstract: A high-resolution digital filter of a type which comprises a memory structure receiving as input a sampled digital signal, and an adder chain with delay blocks therebetween, the adders being connected to memory outputs to convert the input signal into an output signal having predetermined frequency response characteristics, has the memory structure made up of at least one pair of non-volatile memories (3,4) being input each one portion (x(n)1,x(n)2) only of the sampled signal.
