In this article we investigate how thermal noise and thermal distortion play a part in the design of a phono audio signal chain. For our example, we’ll use a Shure M97XE cartridge, a 47K/200pF termination shunt, three gain stages of 10X … Continue reading →
In Part 1 of this Short and Sweet article we derived the formula for thermal noise as it applies to RC filter circuits: \(\displaystyle {{\eta }_{v}}^{2}={{KT}}/{C}\;\) In this blog post, we’ll try out various RC filters using Signal Chain Explorer and … Continue reading →
My Bonnie lies over the ocean. My KT lies over the C … Okay, with that lame joke out of the way, in Part1 of this (perhaps not so) Short and Sweet two-part article, we’ll derive the well-known \(\displaystyle {{\eta }_{v}}^{2}={{KT}}/{C}\;\) equation, … Continue reading →
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 →
Our new product Signal Wave Explorer will soon be ready for sale. It was a long and unexpected journey developing this product — unexpected because we weren’t quite sure when we started what the program would be capable of, and we … Continue reading →
