Implementation of `Fiter_PT1: Providing PT1 Transfer Function' Function Block. The Filter_PT1 function block provides a PT1 transfer function. The output value increases to 63% of input value within the time period equal to filter time constant. The output value reaches to 95% of input value after the time period equal to 3 *Filter time constant and then reaches gradually to 100% of the input value. This Function block is a part of a Tool Box library in which function blocks which are widely used in various applications in various industries are developed.
