Ratio Bias Block

Purpose

The Ratio Bias (RB) block lets you change an incoming signal by adding a constant (bias) and/or by multiplying by a constant (ratio). The block calculates the constant by subtracting an offset from the signal.

The following equation illustrates this method:

Output = Ratio (Input - Offset) + Bias

NOTE: This is a variation of y = mx + b.

Features

The Ratio Bias block:

• Is a control block.
• Is a secondary block.
• Can be used in a chain with exception-based or time-based processing.
