Designing total-harmonic-distortion (THD) measurement into a system usually involves a notch filter and a broadband ac measurement. The problem with this technique is that it measures both THD and ...

Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD). Makes sense, because THD affects the quality of audio reproduction. However, THD can also ...

The new FSMR Measuring Receiver from Rohde & Schwarz is designed to calibrate all key parameters of signal generators and fixed and variable attenuators. It combines a level calibrator; AM, FM, and PM ...

Rohde & Schwarz’ optional harmonic filters for its SMB100A microwave signal generator make it possible to achieve harmonic suppression of more than –50 dBc over a frequency range of 150 MHz to 40 GHz.

The author is technical publications manager and a senior technical writer at Audio Precision in Beaverton, Ore. When reduced to its basics, the process of audio test and measurement is concerned with ...
