Frequency modulated signal generation
Keywords:generation, direct digital synthesis, DDS, frequency modulated signal
Compound frequency modulated signal generation process with simple integrated direct digital synthesis microcircuit is presented starting DDS microcircuit choice, time and modulation characteristics analysis, interface up to working model, control program design and frequency modulated signal generation. The experimental research results are in agreement with test signal spectrums theoretical computation. The compound frequency modulated signal generation possibility using simple integrated DDS chips circuits is proven
