O2 Sensor plant model development

Hi,

I am developping O2 sensor simulink model which is used in gasolin engian.

I am trying to prefilter input sensor data (AFR- lambda).

I want to understand two methods:

1. Input λ differentiation processing and limiter setting
2. Input λ differentiation processing and attenuation processing

by which I can filter my sensor data effectivley.

With Regards,
