Hello.
I trying to construct a evaluation platform for data converters, which should be capeable of supplying ADCs with different kind of signals to be read and the converters characteristics would be calculated and plotted with the resulting output.
I'll need a good high fidelity sine wave source and I want to ask, how pure or how fine a sine wave can be produced through digital means?
when you hear "pure sine wave" digital isn't the first that comes to mind perhaps, but a analog oscillator would not be as manageable as a digital source. I don't want to have a sine wave of one frequency but it should be tailored to specific converter but I don't know if I can go through digital synthesis at all?
Providing its clean enough for the purpose of characterizing converters I guess that accurate frequency choices and amplitude adjustments is what is needed, analog solutions does provide these but what do you people think about this?
Regards
David
