Hi folks,
I'd made some progress through last post but now I come up with a new idea. To achieve this, let computer produce a constant voltage, and let it be the input of my circuit. The outputs are expected to be Sin(V) and Cos(V). Note that these two outputs are just some number, so V becomes the phase of the two quadrature waveform.
The idea is, by changing the voltage, we can have get arbitary phase we want. Now if I change the voltage, I can change the phase simultaneously. The requirement for this circuit is low-noise. The voltage is around 20KHz
It looks like some lookup table. V--sin(V) and cos(V). Is there anyone can help me with this? Many thanks!
