Overview

The Clip2 block provides asymmetric limits for an input signal. The signal will saturate at a maximum value of (UpperLimit) and a minimum value of (LowerLimit). The input signal is offset by an amount defined by the offset prior to the clipping the signal to the upper and lower limits.

The configuration values for this block are as follows:

UpperLimit	Asymmetric Upper Limit. If Input + Offset < UpperLimit, then Output = Input + Offset If Input + Offset >= UpperLimit, then Output = UpperLimit
LowerLimit	Asymmetric Lower Limit. If Input + Offset > LowerLimit, then Output = Input + Offset If Input + Offset <= LowerLimit, then Output = LowerLimit
Offset	Offset value that is summed with the Input value before clipping the input to the upper and lower limits.
Subsample Code	A code which determines the schedule for updating this block (every sample, even samples only, etc.) See Subsampling.
User Data 0	Application-specific data. See User Data Storage.
User Data 1	Application-specific data. See User Data Storage.

The Output of a Clip2 block is the Input plus the offset clipped by the upper and lower limits.

If Input + Offset < UpperLimit, or > LowerLimit, then Output = Input + Offset

If Input + Offset >= UpperLimit, then Output = UpperLimit

If Input + Offset <= LowerLimit, then Output = LowerLimit

The block has two user data fields (User Data 0, User Data 1) to store application-specific data for convenient storage and retrieval. See User Data Storage for details.

The block's update schedule is determined by the Subsample Code (See Subsampling). The following Parameter Dialog Box can be opened by double-clicking on the block in a Simulink Model:

Description

The Clip2 block provides symmetrical limits for an input signal. The signal will saturate at a maximum value of (+ Limit) and a minimum value of (– Limit). The input signal is offset by an amount defined by offset prior to the clipping the signal to +/- limit.

double

CLIP2().UpperLimit

Asymmetric Upper Limit.

If Input + Offset < UpperLimit, then Output = Input + Offset
If Input + Offset >= UpperLimit, then Output = UpperLimit

double

CLIP2().LowerLimit

Asymmetric Lower Limit. Input + Offset.

If Input + Offset <= LowerLimit, then Output = LowerLimit

double

CLIP2().Offset

Offset value that is summed with the Input value before clipping the input to the upper and lower limits.
