LTspice: Evaluating Electrical Quantities

Sometimes, you need more than the basic circuit analysis and measurements offered by the LTspice waveform viewer. .MEASURE statements enable numerical analysis and can be very powerful in evaluating user-defined electrical quantities such as:

  • Rise, Fall and Time Delay
  • Average, RMS, min, max, and peak-to-peak
  • Find X when Y occurs
  • Derivative and Integral Evaluations

This video provides an introduction to using .MEASURE statements to perform numerical analysis of a circuit in LTspice IV.
