Light Intensity Measurements for Light Emitting Diodes (LEDs)
I was working late one evening last week when the phone rang. I debated whether to answer it or not, because it was well after standard business hours and I was trying to finish a project, but I decided I needed a break from my computer screen. I…

Signal to Noise Ratio
My
last blog explained the difference between single-ended and differential measurements. To follow-up, I want to discuss another key concept in the quest to make accurate and consistent measurements: signal to noise ratio (SNR). I will also re…

A Brief Review of Temperature Measurements
The properties of materials and nearly all biological, chemical, and physical processes are temperature dependent. As a result, temperature is perhaps the most widely measured environmental variable, and there are multiple sensors, or thermometers, a…
