yk = uk uk1,

where uk = u, yk = y and uk1 is the value of input u in the previous cycle (delay TS, which is the execution period of the block).

Input

u

Analog input of the block

Double (F64)

Output

y

Difference of the input signal

Double (F64)

Parameters

ISSF

Zero output at start-up

Bool

off ..

In the first cycle the output will be y = u.

on ...
