| Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below. |

| Noise Undesirable electrical interference to a signal. Sources of noise can include ac power line, motors, generators, transformers fluorescent lights, CRT displays, computers, electrical storms, welders, radio transmitters, and others. Noise Immunity The ability to tolerate noise voltages on its input. Nonvolatile A memory or data storage device that retains its information content when electrical power is removed. Ordinary RAM is volatile whereas ROM, bubble memory, battery backed up CMOS RAM, floppy, and hard disks are nonvolatile. NTSC A 60 Hz standard for encoding color video signals. Used in North America, Canada, Japan, and most of South America. Nyquist Display Function This display function plots the resultant data in complex form, with real components on the
x-axis and imaginary components on the y-axis. It used to assess the stability and performance
of a closed loop system by analyzing the contour of the frequency response function on the
complex plane. Nyquist Sampling Theorem If a continuous bandwidth limited signal contains no frequency components higher than a specified frequency the original signal con be recovered without distortion if it is sampled at a rate of at least twice the specified frequency. |
