A critical view of adaptive filter theory

In this paper we offer a ”birds eye view” of the field of adaptive filtering with the aim of suggesting a new approach to its teaching. Following a brief survey of the diverse lines of thought underpinning the traditional approach to the presentation of the most comm...

The first active tunable wideband impedance matching circuit

The first transistor-based impedance matching circuit for radio-frequency (RF) applications is introduced in this paper. It adapts arbitrary output impedances of RF blocks to desired values between 50ohmand 250ohm, from 0 to 5GHz, while occupying only 0.005mm² of circuit area in a 0.35μ...

New high performance CMOS fully differential current conveyor

In this paper, a new CMOS high performance fully differential second-generation current conveyor (FDCCII) is presented. The proposed FDCCII provides good linearity, high output impedance at terminals Z+ and Z-, and excellent output– input current gain accuracy. What is more, it is opera...

True random number generation based on double-scroll chaotic system

A new random number generator design from a double-scroll chaos is presented. The structure is based on the well-known oscillator sampling technique where the chaotic signal is employed as the entropy source. The proposed random number generator is realized in the laboratory and th...

Phase analysis of interference currents of railway vehicles

Problems with evaluation of phase relations of reverse tractive current produced by railway driving vehicles are described in this article. This evaluation is newly required in innovated standard ČSN 34 2613. The possibilities and problems of phase analysis

The effect of wrist cuff width on oscillometric blood pressure waveforms

Accuracy of blood pressure (BP) measurement with any method is affected by cuff size. Narrow cuff overestimates BP and wide cuff underestimates BP. Wrist cuff oscillometric BP monitors typically use narrow cuffs with bladders about 6 cm wide. The segment of the radial artery c...
