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 ...

This write-up continues the theme of my previous report: distortion correction. That blog addressed the case of steady-state distortion minimization. This month, we look at an idea that addresses the ...

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 ...

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 ...

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 ...
