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)

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.

symbol

Mathematically, SWEEP is calculated as follows:

SWEEP = STEP5(x,0,0,dx,1)* a * sin(2*(freq(x)*x + PHASE(x)))

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)
