Experimenting with Open-Source RF Analysis Tools to Better Understand How Poles and Zeros Relate to Q Factor

At Knowles Precision Devices, we’re all about RF. While we are focused on applying our expertise in ceramics and thin film manufacturing, our engineers also enjoy keeping up with the trends impacting the entire RF “ecosystem.” This includes dedicating time to experimenting with various open-source RF modeling and analysis tools that we think our potential non-design engineer customers might find useful. Recently, we used Python Scipy.signal Toolbox to explore the theory behind poles and zeros.

In this white paper, we will:

• Use the Python Scipy.signal Toolbox to build a transfer function
• Take a closer look at poles and zeros to explore their relationship to Q factor and their function in filter performance
