Zero points:
You can calculate the zero points with the Event Isolation Analysis Object. Choose the event Level crossing and the level 0.
Extension of a signal:
For this purpose FlexPro7 offers the linear or the nonlinear curve fitting. With these analysis objects or these FPScript functions (Approximation, NonLinCurveFit) you can calculate the parameter values of a chosen linear/nonlinear model. With the model and the model parameter values you can create a new signal with more X-values.
Example with a linear model:
Dim s, c, x
s = Signal(Sin(2. * PI * 1.00000000000000 * (1000, 0.000000000000000, 0.0005)), (1000, 0.000000000000000, 0.0005))
c = Approximation(s, APPROX_C + APPROX_X + APPROX_SIN + APPROX_COS)
x = (NumberOfElements(s) * 2, s.X[0], Increment(s))
Signal(c[0] + c[1] * (x) + c[2] * sin(x) + c[3] * cos(x), x)
