DIF – Difference

Block SymbolLicensing group: STANDARD
PIC

Function Description
The DIF block differentiates the input signal u according to the following formula

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)

R1

Block reset (same state as after init)

Bool

HLD

Hold block execution

Bool

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 ...

Zero output in the first cycle, y = 0.
