LTspice Lesson 4c: Generate Waveforms used in Electric Circuits: PWL

by Kashif Javaid Piece-wise linear voltage or current source is very interesting and can be used to create arbitrary waveforms. Basically you define points (tx, vx) to draw out the precise waveform.¬†For times before t1, the voltage is v1. For … Continue reading

LTspice Lesson 4b: Generate Waveforms used in Electric Circuits: PULSE

LTspice has various options to generate a custom pulse for circuit simulations. Generating a pulse is done through an independence voltage or current source as shown below: Pulse minimum voltage, maximum voltage, delay before the pulse start, rise time and … Continue reading
