  • Universal Voltage Conveyor and its Novel Dual-Output Fully-Cascadable VM APF Application 

    Herencsár, Norbert; Koton, Jaroslav; Hanák, Pavel (MDPI, 2017-03-20)
    This letter presents a novel realization of a voltage-mode (VM) first-order all-pass filter (APF) with attractive features. The proposed circuit employs a single readily available six-terminal active device called as ...
  • Validation of Fractional-Order Lowpass Elliptic Responses of (1 + )-Order Analog Filters 

    Kubánek, David; Freeborn, Todd; Koton, Jaroslav; Dvořák, Jan (MDPI, 2018-12-13)
    In this paper, fractional-order transfer functions to approximate the passband and stopband ripple characteristics of a second-order elliptic lowpass filter are designed and validated. The necessary coefficients for these ...
  • The Value of Geographic Locations Submitted by Internet Users 

    Komosný, Dan; Mehic, Miralem (IEEE, 2018-10-22)
    Internet users may be asked to manually provide their contact details including city or full postal address. Examples include use of trial/free applications and services, filling out on-line surveys and petitions, and ...
  • VDIBA-Based Fractional-Order Oscillator Design 

    Kartci, Aslihan; Herencsár, Norbert; Dvořák, Jan; Vrba, Kamil (IEEE, 2019-07-01)
    This paper deals with a voltage-mode integer- and fractional-order oscillator design providing compact and simple CMOS structure. The proposed circuit consists of only one grounded/floating capacitor, one grounded/floating ...

    Článek podrobně rozebírá problematiku videokonferenční technologie. Vysvětluje jednotlivé základní části použitých zařízení a skupin protokolů. V konečné části poskytuje přehled hardwarové a softwarové implementace ...
  • Visible Light Communication: A System Perspective - Overview and Challenges 

    Rehman, Saeed; Ullah, Shakir; Chong, Peter; Yongchareon, Sira; Komosný, Dan (MDPI, 2019-03-07)
    Visible light communication (VLC) is a new paradigm that could revolutionise the future of wireless communication. In VLC, information is transmitted through modulating the visible light spectrum (400–700 nm) that is used ...
  • Visualization Tool for Control Signalling in NG-PON2 

    Horváth, Tomáš; Jurčík, Michal (Croatian Communications and Information Society, 2016-07-01)
    The requirements of end users on the quality of Internet connection and services is forcing the Internet providers and technical community to propose and introduce new technologies which may react to this demand. The most ...
  • A Voltage Gain-Controlled Modified CFOA And Its Application in Electronically Tunable Four-Mode All-Pass Filter Design 

    Herencsár, Norbert; Koton, Jaroslav; Lahiri, Abhirup; Metin, Bilgin; Vrba, Kamil (International Science & Engineering Society, o.s., 2012-10-31)
    This paper presents a new active building block (ABB) called voltage gain-controlled modified current feedback amplifier (VGC-MCFOA) based on bipolar junction transistor technology. The versatility of the new ABB is ...
  • Voltage Gain-Controlled Third-Generation Current Conveyor and its All-Pass Filter Verification 

    Herencsár, Norbert; Kartci, Aslihan; Koton, Jaroslav; Tsirimokou, Georgia; Psychalinos, Costas (IEEE, 2017-09-04)
    The paper presents a new active building block (ABB) called minus-type voltage gain-controlled third-generation current conveyor (VGC-CCIII) in which the voltage gain between Y to X terminal can be controlled. The usefulness ...
