Elektor Academy - AVR Software Defined Radio


This webinar describes signal generation using the DDS principle and N/N+1 division, as well as methods of generating AM and FM modulated signals in the low frequency range. The next part describes sampling and mixing. Down-sampling and the short conversion time of the AVR’s ADC allow signals up to 500 kHz to be digitized. The course covers demodulation of AM, FM and PM signals as well as clock-recovery and error detection.
