Summary

CircuitLab can also handle arbitrary Laplace transform functions, and can produce step response plots in the time domain and Bode plots in the frequency domain.

Description

The Laplace Block element takes an arbitrary polynomial in "s".

A few things to try in CircuitLab

Time-domain simulation

With "Skip initial" set to "Yes", and a 1 volt input voltage source, we'll see the unit step response at the output.

Frequency-domain

The Frequency-domain simulation mode will generate a Bode plot of amplitude and phase versus frequency.

Comments

classic, you can have such fun with this. will need to find a way to simulate a unit impulse
