After discussing lead/lag functions used in feedforward control systems (for dynamic compensation), my students and I simulated one on a breadboard using variable resistors and capacitors. A square-wave function generator serves as the source of input step-change signals, while an oscilloscope displays the lead/lag function output.
@sickboymike The circuit by itself is pretty useless. It does, however, illustrate the operation of a lead/lag function of the type used in "feedforward" control systems to compensate for different lag times in a process control loop. It's hard to explain in 500 characters, so if you want more info you'll probably have to read the chapter in my book on feedforward.

What would be the purpose for this lead lag circuit?
