Digital filtering in VLSI

1986
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), 2013
The 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.

Digital filter with confidence input

2015 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2015
An 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.

The Synthesis of Recursive Digital Filters

Journal of the ACM, 1966
The 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.

Design of Digital Notch Filters

IEEE Transactions on Communications, 1974
It 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 ...

Multirate Digital Filtering

IFAC Proceedings Volumes, 1982
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.

FFT Length in Digital Filtering

IEEE Transactions on Computers, 1979
When 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 ...
