Fast-switching analog PLL with finite-impulse response
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004This paper describes a method for speeding up the linear settling response of integer-N phase-locked loops. Extending the discrete-time model of the PLL first proposed by Gardner, simple design rules are derived which guarantee accurate frequency settling in few reference cycles.

Impulse response approximation of digital finite impulse response filter with delay line units
Automatic Control and Computer Sciences, 2017This article proposes special digital filtering structures formed by one multiplier, one adder and a delay line. Such structures can be used to synthesize finite impulse response Hilbert filter. The advantage of such approach is reduced number of multipliers, compared to standard implementation.

A scheme of PLL with finite impulse responses
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1996Conventional PLL's (phase-locked loops) lack speed, because phase comparators cannot achieve time-continuous operation. Instead, a completely time-discrete scheme, using a special voltage-controlled oscillator and a digital controller, provides for response time of 2 cycles, but with overshoots of 100%.

Finite impulse response hybrid systems
Proceedings of 35th IEEE Conference on Decision and Control, 2002The ramifications of a condensed signal technology and the application of Markov chain methods to system modeling and control are explored. Condensed object-oriented signals are constructed from raw measurement data. Finite impulse response hybrid systems are proposed for process models based upon these object-oriented signals.

Finite Impulse Response Filters
2013Filtering means preserving certain favored signal frequencies without distorting them while simultaneously suppressing others. Although there are many, many approaches to digital filtering, we focus on Finite Impulse Response (FIR) filters. As the name suggests, these filters have no feedback loops, which means that they stop producing output when the ...

Design of finite impulse response deconvolution filters
Applied Optics, 2010This paper describes inverse filters that restore imagery with minimal artifacts. Deconvolution kernels are obtained by windowing Wiener-type inverse filters (WTIFs). Windowed WTIFs exhibit good restoration properties. Constraining the size of the WTIF kernel is necessary because of the edge effects associated with discrete convolutions.

Empirical Bayesian finite impulse response modeling
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004This paper presents a Bayesian modeling technique, called empirical Bayesian finite response (EBFIR) modeling, that helps deal with the collinearity problem usually encountered in FIR models, and helps improve the estimation accuracy of their coefficients.

Finite impulse response ultrasonic transducers
The Journal of the Acoustical Society of America, 1982The conventional thickness mode equivalent circuit of the piezoelectric transducer is analyzed when one face is perfectly well terminated. It is shown that the impulse response of the transducer can be made ideally time limited by inserting a linear network in the electrical circuit.
