This document explores the principles of frequency response in modern control systems, focusing on logarithmic properties and their applications. Key logarithmic rules are detailed, including the logarithm of products and quotients. Additionally, it presents graphical representations of the tangent function versus its angle and the arctangent function versus its input, facilitating a deeper understanding of these mathematical relationships in control system analysis.

Log Rules: 1) logb(mn) = logb(m) + logb(n) 2) logb(m/n) = logb(m) – logb(n) 3) logb(mn) = n · logb(m)
