Description
The Weighted Sample Time Math block adds, subtracts, multiplies or divides its input signal ( ) by a weighted calculation step ( ). If the input signal is continuous, is the calculation step of the model. Otherwise, is the sampling step of the input signal. If the input signal is constant, the block is assigned a final calculation step based on its connection and context.
The block icon changes depending on the operation selected in the Operation parameter and the value of the Weight value parameter.
The mathematical operation is specified by the Operation parameter. The block can also output either a weighted calculation step (Ts Only) or a weighted sampling rate (1/Ts Only).
The weighting factor is specified by the Weight value parameter. If the weight is 1.0, this value is not displayed in the equation on the block icon.
You can use the Weighted Sample Time Math block to extract the calculation step from the signal. To do this, set the Operation parameter to Ts Only and the Weight parameter to 1.0. In this configuration, the unit outputs the calculation step of the input signal.

The block calculates the output signal value using the priority rules for operators. For example, if the Operation parameter is +, the block calculates the output signal as follows:
However, if the Operation parameter is /, the block calculates the output signal as follows:
