Receiving RTTY decoder
 Šuňal, Štefan ; Caha, Tomáš (referee) ; Lattenberg, Ivo (advisor)
This thesis deals with designing and implementing autonomous decoder for RTTY communication. Theoretical part of the thesis deals with researching the RTTY technology and FSK modulation, which it uses, focusing mainly on the methods of demodulation. Next part of the thesis compares suitability of available platforms. Practical part of the thesis describes the design and implementation of circuit board, firmware and computer application. The device is using STM32 microcontroller. Firmware was developed in C++ using Arduino. The computer application was created by using C\# and WPF. 3 methods of FSK demodulations were implmented. One is using a FFT algorithm. Other two calculate frequency based on the period of square signal.
