    The two basic trends of our time are as follows:

    • Everything becomes software defined.
    In Software Defined Electronics (SDE), a brand new approach introduced recently, the telecommunication systems and measurement equipment are implemented in baseband (BB) on a LabVIEW, Matlab or C++ platform and the transformation between the BB and RF/microwave domain is performed by a universal hardware (HW) device. Because SDE implements all signal processing in SW, the SDE approach offers the flexibility required in Cognitive Radio (CR), Software Defined Radio (SDR) and Virtual Instrumentation (VI).

    The teaching material of this subject is completed with the theory and practice of software defined electronics. To equip the students with the required theoretical and practical skill, laboratory experiments are also offered addition to the lectures where a 915-MHz FSK radio link and different QPSK transmitters are implemented and tested. In the radio link built in the laboratory experiment one networking device is implemeneted by a conventional HW-type FSK transceiver (Texas, TRF6900EVM), while the other device is implemented by a Universal Software Radio Peripheral (National Instrument, USRP-292x).

    For further information on the SDE approach refer to the following materials:
