The sources of noise in a signal chain can be either internal or external. Managing noise in the signal chain requires meticulous examination of each circuit in the chain to minimize noise where ...

Part 1 looks at driving high-performance, high-speed ADCs, and benefits to using an input transformer in a differential inverting amplifier design Part 2 looks at adding an interstage filter between ...

We all know what distortion sounds like. We’ve heard it in heavy metal tunes, cheap iPod docks and the crummy speakers at Taco Bell drive-thrus. And we’ve all read distortion specs on things like ...

While many op amps can claim either low noise or low distortion, the AD8099 high-speed op amp promises both. It specifies a voltage noise of 0.95 nV/vHz and a distortion of -90 dB at 10 MHz. Analog ...

When we are concerned with the accurate reproduction of a signal, distortion and noise are the enemy that engineers spend a great deal of time eliminating wherever possible. However, humans being the ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

Recently I've done a collection of measurements and tests on interconnect cables to see what I could find that would explain the sonic differences that many people, including myself, have grown ...

Several readers report poor sound quality from the MacBook Pro's speakers. In particular, some readers are reporting that the right speaker outputs distorted or otherwise poor quality audio while the ...
