Terry,

 

Thanks for the great find. I will listen but won’t have a chance to test anything until the weekend.

I am out of town, and unable to attend this session Tuesday evening at 8PM.  I wanted to pass along the info to people here, like Karl and Alex, who have been playing with AD9850 and AD9851 DDS units.  These Chat With tThe Designer sessions are of interest to homebrewers.

 

I believe there is even an Arduino sketch at the bottom of the whitepage.

Check it out.

Terry, WB4JFI

Episode #55 of Chat With The Designers airs Tuesday (tomorrow) on Teamspeak
at 8pm Eastern, 0000z: Analyze This! ... Direct Digital Synthesis

This time we pick up with the popular "Analyze This!" series again with a
dissection and analysis of the very popular DDS circuits that serve as Local
Oscillators in many of our homebrew projects these days. While the circuits
are relative small and principles of operation are believed to be known by
most, you might find that some design aspects can surprise you. Whether it
is voltage level translation, parasitic oscillations in the post-LPF
amplifier, or high current draw and seemingly excessive package
temperatures, this episode of CWTD is likely to give you additional
considerations when selecting and using a DDS circuit for your next project.

The whiteboard we use during the live audio program is at .

To participate, all you need is a microphone and a computer connected to the
Internet. The easy instructions for getting on with Teamspeak are at .

See you on the show tomorrow evening!

73, George N2APB & Joe N2CX
