On Exponential Digital Filters
Journal of the ACM, 1959This paper derives the weighting sequence of a linear digital filter whose output is an estimate of the predicted values of the derivatives of the input. The input functions considered are arbitrary linear combinations of n + 1 known functions, plus a random stationary signal and a random stationary noise component.

In this paper we take a first step in the study of VLSI realizations of digital filtering. For increasing input rate. processing is feasible only by resorting to massive parallelism, i.e., to an nq-th extension of the original order-n filter. We show that the operation is reducible to convolutions with fixed n-vectors and propose to realize the ...

Method to convert analog filters to digital filters
2013 8th International Symposium on Image and Signal Processing and Analysis (ISPA), 2013The analog filters are usually converted to IIR digital filters using appropriate transformation of system function from s-domain to z-domain. Recently another approach of converting an analog filter described by a diagram or a netlist to a digital filter has been proposed.

The Synthesis of Recursive Digital Filters
Journal of the ACM, 1966The circumstances and methods of the synthesis of linear digital recursive filters which are both stable and physically realizable are described. It is shown that any amplitude requency transfer function expressible as an even trigonometric rational polynomial can be synthesized by a real stable linear digital recursive filter.

Digital filter with confidence input
2015 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2015An extension to standard digital finite input response low-pass filters is proposed, allowing full suppression of noise peaks at the expense of gradually decreasing broadband noise-suppression performance. Each input sample is associated with a confidence value, where zero-confidence samples must not contribute to the filter output.

Abstract Multirate filtering arises naturally in digital signal processing as an adaptation of the sampling rate to the banwidth of the signal at each step of the processing. It results in a significant reduction of machine complexity in many cases of practical importance.

Design of Digital Notch Filters
IEEE Transactions on Communications, 1974It is shown that a second-order digital notch filter is uniquely characterized by two distinct parameters, the notch frequency and the 3-dB rejection bandwidth. As a result, such a filter can be realized using only two multipliers. Methods are outlined to design a notch filter for a prescribed notch frequency and a prescribed 3-dB rejection bandwidth ...

FFT Length in Digital Filtering
IEEE Transactions on Computers, 1979When the FFT is employed for nonrecursive digital filtering, the time required to process one block of input data, N samples long, is often approximately of the form N(logr (N) + Q), where Q ≥ 0. Earlier results on determining optimum N have assued Q ≥0, becauese it has long been informally observed that typically little is to be gained by taking the ...

IEEE Transactions on Audio and Electroacoustics, 1968
Digital filtering is the process of spectrum shaping of signal waveforms, using digital components as the basic dements for implementation. This process is extensively used in the computer simulation of analog filters. The unmistakable trends toward increased speed and decreased cost and size of digital components make digital filtering especially ...
