LTspice: Importing and Exporting WAV & PWL Text Files

Simon Bramble - Field Applications Engineer Jan 20th 2016

Sometimes you may want to apply a voltage source to your circuit whose characteristics have been derived from an external source whether it is a WAV file or a just a list of time and voltage instances. LTspice allows you to do this and this video will highlight how to import and export WAV audio files as well as how to read a list of piecewise linear values from a text file to create infinitely complicated stimulation voltages.
