An analog-to-digital converter (ADC) sampling rate is determined by a clock signal that controls how often a voltage snapshot is taken for each conversion. However, clock signal timing isn’t perfect, ...

Figure 1 depicts the nature of the information provided by measuring a signal in the time domain vs. the frequency domain. Both provide insight into the content of the signal and possible approaches ...

According to the Occupational Safety and Health Administration, 22 million people—including nearly all power plant workers—are exposed to potentially damaging noise at work each year in the U.S.

In order to control noise, designers must first determine where the noise source or sources are how much each is contributing to the overall level, and their frequency signatures. In order to control ...

A white-noise source can be constructed based on the random noise of a Zener diode or reverse-biased base-emitter junction. While these circuits work, they are temperature sensitive and not ...
