• The design of a telemetry system for Grumeti reserves 

      Labuschagne, Adriaan S. (Stellenbosch : University of Stellenbosch, 2006-03)
      This thesis covers the design and development of a radio telemetry system to assist in management of the Grumeti reserves. This was accomplished through the integration of a digital data transmission system into the ...
    • The design of CAN nodes for minimising cables on the SUNSAT's TCMD system 

      Musetha, Rendani D. (Stellenbosch : Stellenbosch University, 2003-12)
      ENGLISH ABSTRACT: The aim of this thesis is to investigate a design of a microcontroller based embedded system that will be used to minimise cable harness on the SUNSAT micro-satellite. The system is called CAN node. The ...
    • The determining of optimum protocol strategies for half-duplex telemetry communication links 

      Wolhuter, Riaan (Stellenbosch : Stellenbosch University, 2002-12)
      ENGLISH ABSTRACT: Though not so prominent as the wide band, high speed, mainstream development of data communication networks, cost and particular bandwidth limitations, still ensure extensive and continuing use of ...
    • Investigation of a high-speed serial bus between satellite subsystems 

      Retief, Francois (Stellenbosch : Stellenbosch University, 2003-04)
      ENGLISH ABSTRACT: The aim of this thesis is to investigate the implementation of a high-speed serial bus based on the IEEE Std 1394-1995 specification for use in a microsatellite. Earth observation microsatellites carry ...
    • Microwave data transmission by means of an optimal bandwidth multichannel QPSK system 

      Malan, Jacques de Villiers (Stellenbosch : Stellenbosch University, 2004)
      ENGLISH ABSTRACT: The increase in the complexity and functionality of new satellites leads to a growing demand for a digital communication system operating at a much higher bit rate than before. The main purpose of this ...
    • Ripple compensation for a class-D amplifier 

      Cox, Stephen M.; Mouton, H. du Toit (Society for Industrial and Applied Mathematics, 2015)
      ENGLISH ABSTRACT: This paper presents the first detailed mathematical analysis of the ripple compensation technique for reducing audio distortion in a class-D amplifier with negative feedback. The amplifier converts a ...
    • Satellite data transmission by means of a multi-channel system 

      Smith, David (Stellenbosch : University of Stellenbosch, 2006-12)
      The aim of this thesis is to find an a ordable and upgradeable manner of increasing the data rate of current satellite systems. The compression, modulation and amplification techniques and telecommunication regulations ...
    • Slotted time based protocol and polling strategies for low speed, narrow band applications 

      Ragadza, Ntakadzeni Ronald (Stellenbosch : Stellenbosch University, 2004-10)
      ENGLISH ABSTRACT: This thesis investigates and develops some aspects of low speed wireless telemetry applications. The system configuration is one of a single master, controlling and communicating with multiple slave ...
