In electrical engineering, taking an AC circuit and deriving the gain, input impedance or what have you is always tedious and error prone. LaSolv takes a SPICE like description of your circuit and solves for whatever parameter you specify- voltage gain, trans-impedance, input impedance, etc.

Features

  • Uses SPICE-like circuit description that's familiar to most electrical engineers
  • Can simplify the equations given component values
  • Runs fast and on the common platforms- Windows, MacOS, Linux
  • Plots the solution- magnitude and phase or real and imaginary
