Hello guys,
I have a little problem with the sine wave from NCO generator. Schematic: https://alteraforum.com/forum/attachment.php?attachmentid=13827&stc=1 I want to produce a 0.5 MHz 10bit sine wave. On the oscilloscope i get something like this: https://alteraforum.com/forum/attachment.php?attachmentid=13829&stc=1 I am using DE0-CV BOARD with ladder 10 bit DAC. It seems to be a problem with the sign of amplitude but how to resolve it. Thanks for any suggestions :)Link Copied
