This audio quality measurement Application Note is geared towards describing the methods for measurement of key audio specifications. Each analysis technique described here in, can be applied to audio ADCs, DACs, Analog Mixers, or any signal within the audio band. Audio quality is typically gauged by three main components. They are Signal to Noise Ratio, Total Harmonic Distortion, and Frequency...

The main focus at Boulder was on experience with hydrological applications of the international standard ISO 9002 and developments i...

The importance and necessity of end-to-end fault and performance problem detection in wide area production networks increases with the complexity of the paths, the diversity of network components performance, and dependency on the network. Network monitoring provides insight into the state and performance of the network and whether it is behaving as expected and whether changes in the network h...

It is well-known that many sub-attributes of line quality, such as edge raggedness, line waviness, etc., contribute to the perception of the overall line quality. But the relative importance of these sub-attributes is not clear, nor is there a method available for combining them into one representative number for overall line quality. To address these issues, we have designed and conducted a se...
