  • A Simple Digital Adaptive Antenna Based on Undersampling 

    Pomenka, P.; Raida, Zbyněk (Společnost pro radioelektronické inženýrství, 1997-12)
    A simple adaptive antenna based on the pilot signal method is described in the presented paper. The system consists of coherent mixers, which shift RF signals into IF band, of sampling amplifiers and A/D converters, which ...
  • Stability of DC Operating Points 

    Valsa, J. (Společnost pro radioelektronické inženýrství, 1997-12)
    DC operating points of a linearized noninertial network can be, according to the character of their stability, classified into 3 categories: 1. stable, 2. unstable, 3. conditionally stable (conditionally unstable). In the ...
  • The Tesseral Processor for Image Processing Based on Hierarchical Data Structures 

    Harakal, M.; Chmurny, J. (Společnost pro radioelektronické inženýrství, 1997-12)
    This paper describes the design and hardware implementation of the Tesseral Processor (TP) with Programmable Logic Devices (PLD). The TP can be used for image processing based on hierarchical data structures as Linear ...
