A key feature of Signal Chain Explorer (SCE) is its built-in ability to calculate and display the thermal noise in your signal chain. In this article, we take a look at thermal noise and how it is modeled and displayed … Continue reading →
In this Short and Sweet blog post we’ll take a quick look at using Signal Chain Explorer to analyze a simple vinyl-to-digital audio signal chain, consisting of a Shure M97XE vinyl cartridge pickup, a twisted pair connection to a parallel RC … Continue reading →
A new feature of Signal Chain Explorer (SCE) is the ability to use LC balun circuits. In this Short and Sweet article we’ll show how SCE can be put to use in inspecting the behavior of these strange but useful creatures. What Be … Continue reading →
We’ve been busy the past few months updating the Signal Chain Explorer program. Even though this is a “point-release”, a ton of new features have been added. Here are the highlights: Numerous new filter stages: Sallen Key low pass, high … Continue reading →
Introduction In this Short and Sweet article, we showcase the ability of Signal Chain Explorer (SCE) to model electric field interference (EFI) in a circuit. We use a simple signal chain composed of a sensor, amplifier, and A/D converter. To simulate EFI, we … Continue reading →
In this Short and Sweet post, we take a brief look at how capacitors work and derive the formula for capacitor impedance, using Euler’s formula for complex exponentials. This post is a paraphrased excerpt from SWE Lesson 1.2. A capacitor stores charge in the form … Continue reading →
We are starting an on-going series of articles called Short and Sweet articles. These are meant to be brief discussions of narrowly-focused topics. You can see all of these articles collected together at the following link (which can also be found … Continue reading →
We are pleased to announce the addition of another lesson in the SWE Lesson Series, this one on low-pass-filtered trapezoid signals. It’s available in PDF form on the Downloads Page, or you can get it directly from the following link: … Continue reading →
Included in Signal Wave Explorer are a set of canned examples that showcase the power of SWE in creating various types of circuit simulations. Many of these examples also illustrate common pitfalls that can trip up the unwary circuit designer. … Continue reading →
Our new product, Signal Wave Explorer (SWE), gives you the ability to run circuit simulations and predict output waveforms. Those of you familiar with Spice tools might think we are doing these simulations using some version of Spice. But we’re not — … Continue reading →
