Youth researchYoung scientists honored
A robotic sparring partner for boxing training, the Internet of Things for the home or a camera that always shoots blur-free films thanks to motors and position sensors - the creativity of the young researchers at the 51st national finals knew no bounds. Now the winners have been announced.
If you want to transmit data, listen to the radio or use a radio, you can use a so-called 'Software Defined Radio' (SDR). The signal processing of these high-frequency transmitters and receivers is carried out using software. The advantages are a reduced device infrastructure and good adaptation to changing transmission standards. Lukas Lao Beyer (18), the national winner in the technology category, has developed a low-cost SDR. In principle, an SDR consists of an antenna for transmitting and receiving data and an analog-to-digital converter. The input signals are processed in a processor and forwarded to a PC via a USB interface. The young researcher realized the SDR on a printed circuit board. The aim was to ensure good signal quality and to develop the software in such a way that large amounts of data can be transmitted in real time.
