The block implements the operation of selecting a fractional part of the input signal. The fractional part means the difference between the signal and its integer part. The fractional part of a positive number is non-negative and the fractional part of a negative number is non-positive (see figure):
Figure 1. Demonstration of the block operationAlgorithm for calculating the fractional part of the number:
where y(t) is the output signal, u(t) is the input signal of the block. In the case of a vector input signal, the block implements the operation of selecting a fractional part of each of the elements of the input vector value.
Inputs
input - input signal.
Outputs
output - output processed signal.
Properties
none
Parameters
none
Note:
dimension of the output signal is always equal to the dimension of the input signal.
