Did you know that you can use LTspice to do Digital Signal Processing (DSP)? Actually, I should say it is useful for validating the operation of a signal-processing algorithm under development. This ...

Usually, with Circuit VR we look at some circuit in detail with simulation — usually LTSpice. This one will be a little meta because I wanted to look at a capability in LTSpice which ironically is ...

LTspice makes it easy to create and simulate schematics quickly. Sometimes the best starting point for hashing out a design is to use ideal circuit elements. However, a circuit designer will need to ...

This way, 10 simulations will be run, each with a different resistance value between 1 KOhm and 10 KOhm. As usual, the different behaviors will be studied with the LTspice and ngSpice software.

What is a transfer function? How to implement a Laplace transform in LTspice. Analyzing transfer functions in the frequency and time domains. Looking at compensator design in LTspice. Transfer ...

One of the good things about simulating circuits is that you can easily change component values trivially. In the real world, you might use a potentiometer or a pot to provide an adjustable value.
