Electronic Acronyms and Terms for [N] Description Other Electronic Terms Somewhat Related;

N ISDN

"Narrowband ISDN"
- The first ISDN services that were developed are now called Narrowband ISDN because they have a lesser data transmission rate than the newer Broadband ISDN
 

N-Type Semiconductor

- A semiconductor where there are more free electrons than holes

Necking Down

- Reducing the conductor trace width from a wide to narrow cross section  

Negative Feedback

- Feeding a signal back to the input of an amplifier that is proportional to the output signal. The returning signal has a phase that opposes the input signal.  

NET

- Common electrical connection between two or more device contacts or leads

network, networks

Network

- A network is a group of computers linked together with cable. The most common form is a LAN (Local Area Network) where electronic mail and other files can be exchanged between

networks

Networks

- Two or more devices interconnected in a single component package

3gpp, axis, computer security, ioca, mi6

Neutral Wire

- The conductor of a poly-phase circuit or a single-phase three wire circuit that is intended to have a ground potential. The potential difference between the neutral and each of the other conductors are approximately equal in magnitude and equally spaced in phase  

NFS

"Network Filing System"  

NICAD

"NIckel CADmium"

- A type of rechargeable battery

 

NICAM

"Near Instantaneous Compounded Audio Multiplex"  

Nickel Barrier

- Plated nickel alloy on the end cap contacts of passive devices to prevent the migration of silver palladium termination material  

NICQA

"National Inspection Council Quality Assurance"  

Night Service

- PABX feature. One of two modes of operation usually equating to attended service to allow one set of PABX programming options to be used.

day service

Niir

- Russian Scientific Research Institute of Radio Communications  

Ninhydrin

- Is most commonly used to detect fingerprints, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin  

NIO

"National Intelligence Officer"  

NOAA

"National Oceanographic and Atmospheric Administration"  

Node

- Common point of contact for testing a circuit assembly

ac ground, binary tree, coupling capacitor, floating load, virtual ground

Noise Figure

- Measure of the noise contribution in an LNB. The lower the figure the less noise contribution.  

Noise Temperature

- Noise measurement of a system as the absolute temperature of a relative source delivering noise power.

gt

Non-Inverting Input

- The input to a diff amp or an op amp that produces an in-phase output  

Nonlinear Device

- A device that has a graph of current versus voltage that is not a straight line. A device that cannot be treated as an ordinary resistor.  

Normalise

- Is to represent a number in an agreed floating point notation in order to avoid
the problem of multiple representations. The form chosen is usually that which
provides maximum precision.
 

Normalized Variable

- A variable that has been divided by another variable with the same units or dimensions  

Notch Filter

- A filter that blocks a signal with at most one frequency
