With new technologies of programmable circuits, their use also spread to the field of communication systems. In thesis, we describe basic building blocks of software defined radio with their interactions. There are examples of digital filters, synthetic generator and demodulation techniques. For demonstration we developed and manufactured a circuit, where we have basic building blocks of software defines radio implemented in FPGA. With built receiver we show how to receive radio stations in the frequency of ultra-short waves (UKW) band with frequency modulation.
