![]() ![]() 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. Run the simulation for Bode plot of Vout and compare with your hand calculation. Usually denoted as \(H(s)\) or \(H(j\omega)\). 2) Make sure to set AC voltage equal to 1. ![]() 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. 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. But we will cover the basics of how to bode plots for both magnitude and phase angle, explaining each step along the way. The bode instrument plotter controls 1 sinusoidal input, linearizing the circuit and performs an AC analysis. I have not had time to look at your circuit, but here is what happens with the bode plotter. The aim of this page is to explain Bode plots as simply as possible. 08-11-2011 05:34 PM Options Please no dead chickens this is a family friendly forums page.
