Signal compression is an appealing technique to use in mixed-signal ATE (automated test equipment) systems because it can reduce the cost of test while improving tester performance. Unfortunately, ...

Electrocardiogram (ECG) signal compression techniques are essential for the efficient storage, transmission and real‐time processing of cardiac data. Advanced methods utilising discrete wavelet ...

Electroencephalography (EEG) signal compression techniques have evolved considerably over recent years, addressing the critical challenge of managing the voluminous datasets generated by ...

ST. LOUIS, MO — More and more Americans are tuning in and turning on to HDTV. And those with cable and satellite service aren’t always happy with what they see. As HDTV has hit the mainstream, viewers ...

Compression algorithms for speech, audio, still images, and video are quite complicated and, more importantly, nearly always lossy. Thus, samples often change dramatically once they’re decompressed.

The purpose of this study is to find a stable spectral feature and illustrate the usability of this feature in compressing the original signal. The compression method is suitable for vibrotactile ...

In a previous article, we discussed analog audio SNR concepts. As mentioned, the dynamic range is restricted at the top by clipping (THD ≤1 percent) and at the bottom by the thermal noise combined ...
