Building on last month’s discussion of resistor noise, let’s check out some basics of amplifier noise. The non-inverting op amp configuration is most common for low noise applications so we’ll make ...

I can't seem to solve this nagging problem. I practice guitar a lot when I'm sitting in front of the PC, as I'll be reading online tab, jamming along to MP3s, etc. Unfortunately, this also causes a ...

Lehle has unveiled the Little Dual II, a passive ABY switcher designed to make selecting between two connected guitar amplifiers quick and painless, with a high-end transformer isolating both A and B ...

When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

As noted by Daniel Defoe and Benjamin Franklin, there are only two things that are certain in life: death and taxes. Unfortunately for those that design or use electronics, there is another: noise.

Why the fresh emphasis on low-noise amplification? Some of it is an issue of signal-to-noise ratio (SNR). Today, sensor voltages and device operating voltages are lower than they used to be, so noise ...
