SWEEP
Returns a constant amplitude sinusoidal function with linearly increasing frequency.
Format
SWEEP (Independent Variable, Amplitude, Start Value, Start Frequency, End Value, End Frequency, Delta X)
For example:
SWEEP (x, a, x0, f0, x1, f1, dx)
Arguments
Independent Variable or x | Independent variable. |
Amplitude or a | Real variable that specifies the amplitude. |
Start Value or x0 | Real variable that specifies the independent variable value at which the SWEEP function begins. |
Start Frequency or f0 | Real variable that specifies the initial frequency. |
End Value or x1 | Real variable that specifies the independent variable value at which the SWEEP function ends. |
End Frequency or f1 | Real variable that defines the final frequency. |
Delta X or dx | Real variable that specifies the interval in which the SWEEP function becomes fully active. |
Note: | Error message will be triggered if  . |
Equation
Mathematically, SWEEP is calculated as follows:
Example
The following function defines a sinusoidal function with a frequency increasing from 2 to 6Hz within the time interval 0 to 5:
SWEEP(TIME, 1.0, 0.0, 2.0, 5.0, 6.0, 0.01)
