Need to compare two X-Y plot to see whether one is crossing the other.

Hi,

I have 4 channels lets say X1, Y1, X2, Y2. Channel length for X1 and Y1 is 10, while for X2 and Y2 is 500.

I want to check whether the second XY plot crosses the first or not. Is there a method to do this?

Pls let me know if you have any queries.

Regards,

Fazil Shah.
