Hi..I am new in this site..There are very useful informations..Thanks..
I need a pic model that I want to get 2 sine signal and compare them about their phase difference?And I want to use the pic to generate 40 kHZ frequency..Do you have any idea about this?
Thanks for your help..
Thanks..Yes,I will use ultrasonic sensors with my pic..And ı want to compare two signal in my pic..One ADC and 2 analog input is enough for this process?
I don't see where you need analogue inputs at all? - like I said, convert the inputs to squarewaves and compare those. However, I'm a little confused about the two waveforms to compare anyway - why two?.
What Nigel is saying is that you don't need analog to determine phase relationship of 2 sine waves. Think about it - how could you represent the phase relationship digitally.
