A low-distortion oscillator is necessary for testing today'sADCs (analog-to-digital converters) that have resolution higher than 20 bits.Low-distortion amplifiers with THD (total-harmonic distortion) ...

As a former telecommunications electrical engineer, I come from a profession where analytical analysis and measurements are a necessity when designing a new product. Working for one of the largest ...

Maintaining a radio facility is an ongoing process, and even new facilities have maintenance needs. Some aspects of equipment performance can be verified through the equipment’s front-panel display, ...

The ability to faithfully digitize a sine wave is a good measure of the fidelity of a high-resolution ADC. Testing this ability on an 18-bit ADC demands a sine-wave generator with residual distortion ...

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

Please provide your email address to receive an email when new articles are posted on . Objective measures of contrast sensitivity and visual distortion can be used to assess the impact of macular ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion ...

Total harmonic distortion (THD), is a popular measure of nonlinearity of a device. Learn about the considerable flexibility in defining THD while providing a relatively simple way to orchestrate all ...

THD + Noise (at -3 dB FS)This measurement indicates how much Total Harmonic Distortion and Noise is present in the cards output signal. Harmonic distortion presents itself as multiple odd and/or even ...

This paper considers linear regression models when neither the response variable nor the covariates can be directly observed, but are measured with multiplicative distortion measurement errors. To ...

The Fraunhofer Institute for Nondestructive Testing IZFP carries out research and development activities in the field of nondestructive testing processes along the entire materials value chain. For ...
