Good morning people! Im a new guy learning about DDS generators. I am working on a DDS project for generating sine, trangular and square waves with AD9833 DDS programmable generator. My problem is that i have a bit of noise over my output signals (though i have built the evaluating board with all those decoupling capacitor i found on page 22 of the datasheet). Does anyone know how can i improve my signals quality?
