Phase modulation of the Analog Devices AD9833 DDS

Published on Apr 23, 2018 DutchBigEd

"This is a short demo of phase modulation of the Analog Devices AD9833 DDS chip with an Arduino (Atmega328p).
First part is where the hard sync input frequency is varied, than the phase of the hard sync is modulated en than the frequentie of the ad9833 is modulated.

The last part all three variables are modulated.

The sync input is PD2 (INT0), the phase
