The quality of sound reproduced by an audio amplifier, measured by critical performance parameters such as THD (Total Harmonic Distortion), damping factor (DF), and T-IMD (Inter-modulation Distortion) ...

O. Shimbo, and W. L. Cook, in the COMSAT Technical Review. 3 Shimbo et al. provide a computational method to estimate the undesired interference caused by intermodulation products of angle-modulated ...

$3,500 is a lot of money for a hybrid digital power amplifier. The NAD M23 is not your typical hybrid digital power amplifier. Not a chance. I’m must confess to being very ambivalent about “hybrid ...

Unless you are a hermit or a Stylite, robust interaction with your neighbors is usually a good thing. Of course, this is not the case with broadcast transmitters, where living in isolation is usually ...

Zero-drift amplifiers dynamically correct their offset voltage and reshape noise density. Two commonly used types—auto-zero amplifiers and choppers—achieve nanovolt-level offsets and extremely low ...

A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

Bi-words seem to be proliferating these days (bi-coastal, bipolar, etc.), and the world of stereo and home theater loudspeakers is no exception. The terms “bi-wiring” and “bi-amping” (short for ...
