2Function

The <filter_FO> block corresponds to a first-order low-pass filter, with a time constant “τ” in seconds.

When the “out” output is invalid (which is the case on the first execution), the filter is initialized with the “in” input.  

3Inputs

• •« in » : Main input. The default value is 0 (type: int) 

• •« τ » : Time constant (in seconds). The default value is 1 s (type: int) 

4Output

• •« out » :  Low-pass filter output 

5Types 

Inputs must be of type: int or float.

The output is of type float.

6Usage

Warning: If “τ” equals 0, this causes a division by zero, so the “out” output will be invalid.
