RJM's Demo of Frequency Response of Systems
The user can select one of various systems, whose block diagram is depicted, where integrators are represented by 1/jω.
By clicking on the blocks in the diagram you can change parameter values. The system transfer function is also shown.
The system's frequency response is plotted : specifically graphs of log(Gain) vs log(ω) and Phase varies with log(ω).
The user can select whether the asymptotic gain and phases are added to the plots.
You can enter the minimum/maximum angular frequencies, or ask that these are calculated automatically.
