It’s these harmonics generated within the amplifier that are referred to as harmonic distortion, and they are measured by feeding a pure sine wave into the device and measuring the ration of ...

The presentation of loudspeaker measurements varies wildly from manufacturer to manufacturer. This means that, without independent analysis, consumers are left comparing specifications that were ...

To measure this distortion, you can use a mixed-signal-THD (total-harmonic-distortion) analyzer to monitor the fundamental frequency amplitude and the second-, third-, fourth-, and fifth-harmonic ...

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 ...

This is a dynamic power measurement adopted from the car industry similar to IHF method, only a bit more difficult for an amplifier and more representative of real musical content. Keep in mind most ...

The harmonics calculation option adds THD measurement parameters to the Numerics table display. As with other numerics table parameters, users may observe the per-cycle behavior of these ...

Measuring an op amp’s THD (total harmonic distortion) at frequenciesbelow 100 kHz is problematicbecause modern amplifiers have a THDrating that is much lower than that ofmost test equipment. The ...

Pioneer Electric&Research has introduced a hardened digital multimeter featuring total harmonic distortion measuring on AC voltages. The Model PDM-550 has been designed for flight-line maintenance ...
