  • Digitally Controlled Linear Four-Port Network 

    Kolka, Zdeněk; Michalek, V. (Společnost pro radioelektronické inženýrství, 1994-09)
    The paper deals with the design of a universal linear multipart. The circuit is based on digitally controlled multiple voltage-controlled voltage sources (MVCVSs). The main advantages of this control are accuracy, ...

  • Function Generator of Programmable Waveforms with Very Long Period Controlled by the Input Signal 

    Krejci, L. (Společnost pro radioelektronické inženýrství, 1994-09)
    The paper deals with design of slow generator of periodic waveforms the shape of which can be changed. The generator with the period adjustable by control signal could provide wide application.

  • New Version of the COCO Program 

    Cajka, J.; Fencl, F. (Společnost pro radioelektronické inženýrství, 1994-09)
    The new version of the COCO program enables the analysis of linear circuits in symbolical, symbolic numerical or in semi-symbolical form. Simple synthesis problems can also be solved with the aid of this program. Several ...

  • DC Analysis of an Ideal Diode Network Using Its Decomposed Piecevise-Linear Model 

    Brzobohaty, J.; Pospisil, J.; Kolka, Zdeněk (Společnost pro radioelektronické inženýrství, 1994-09)
    A new method of finding the operating points in circuits containing ideal diodes which utilizes the decomposed form of the state model of an one-dimensional piecewise-linear (PWL) system is developed. The universal procedure ...

  • Atmospheric Optical Communications 

    Wilfert, O. (Společnost pro radioelektronické inženýrství, 1994-09)
    This article contains a description of a digital atmospheric optical link (DAOL). DAOL may find LAN applications as bridger between buildings containing cable subnetworks or as temporary quick-connects for which cable runs ...

  • Comparison of Adaptive Antenna Arrays Controlled by Gradient Algorithms 

    Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 1994-09)
    The paper presents the Simple Kalman filter (SKF) that has been designed for the control of digital adaptive antenna arrays. The SKF has been applied to the pilot signal system and the steering vector one. The above systems ...
