In terms of circuits this means we might have a \(V_\) (depending where the constant lies. Generally a transfer function is equivalent to the ratio of an output to an input. Usually denoted as \(H(s)\) or \(H(j\omega)\). Q: What do we need to start doing the Bode Plots?Ī: The first thing we’ll need is called transfer function. One we’ll call the magnitude plot and one called the phase angle plot. In this set of notes we will call \(\omega\) our input frequency.īode plots typically consist of two graphs. This system could be any system (not just a circuit!) which experiences change in behavior due to a change in frequency (cycles/second).įrequency Response basically means how our system will change with respect to a given input frequency. This is called the frequency response of the system. Let’s get started by first answering a few questions.Ī: Bode plots are a actually a set of graphs which show the frequency response of a system. AbstractFor the development of dynamic systems in electrical engineering, control engineering, and even mechatronics, the steady-state response at the output of the system to harmonic excitation (sinusoidal oscillation) at the input often must be known. But we will cover the basics of how to bode plots for both magnitude and phase angle, explaining each step along the way. The aim of this page is to explain Bode plots as simply as possible. However, we will want to be able to display a large range of. A Beginner's Guide to Bode Plots Zac Blanco Blog Education Projects About A Beginner's Guide to Bode Plots A Bode plot is simply a plot of magnitude and phase of a tranfer function as frequency varies.
