Power Function
Computes power function of signal samples
Category: Math
Description:
Power Function block implements three different mathematical operations according to the parameter set. Figure 1 shows the Power Function Properties tab and the available functions.
Figure 1 - Power Function block dialog
The second and third function options, i.e. u^n and u^(1/n) respectively, require an additional parameter n to be defined in the dialog. Figure 2 shows an example using all functions. When applicable, parameter n = 2.
Figure 2 - Different applications of the Power Function block
The Power Function block cannot perform mathematical operations which result in complex numbers.
Figure 3 shows an example. Mathematically, the result should be

Parameters:
The user can choose among three functions to be executed:
- e^u - Returns the Euler's number raised to the power of the Input Signal value.
- u^n - Returns the Input Signal value raised to the power of the parameter n.
- u^(1/n) - Returns the n-th root of the Input Signal value, according to the parameter n.
Ports:
Input
Signal used in the power function operations.
Data Types:
Output
