Computer set for processing radio signals

The work relates to digital signal processing of radio frequencies. Developed and implemented a computer program that allows to work with radio signals, ie. filtering, demodulation, strengthening and radio physical system whose task is to match the radio frequency range from 0 to 30 MHz for the possibility of processing them into discrete signal by the analog to digital which is standard equipment on every sound card of the PC. The use of the computer significantly expanded capabilities of the system and provided the ability to preview spectrum radio signal on the basis of which it is possible to assess the type and quality of the received signal.
