line noise

[′līn ‚nȯiz]
(communications)
Noise originating in a transmission line from such causes as poor joints and inductive interference from power lines.

1. Spurious characters due to electrical noise in a communications link, especially an EIA-232 serial connection. Line noise may be induced by poor connections, interference or crosstalk from other circuits, electrical storms, cosmic rays, or (notionally) birds crapping on the phone wires.

2. Any chunk of data in a file or elsewhere that looks like the results of electrical line noise.

3. Text that is theoretically a readable text or program source but employs syntax so bizarre that it looks like line noise. Yes, there are languages this ugly. The canonical example is TECO, whose input syntax is often said to be indistinguishable from line noise. Other non-WYSIWYG editors, such as Multics "qed" and Unix "ed", in the hands of a real hacker, also qualify easily, as do deliberately obfuscated languages such as INTERCAL.

They always assumed that an uncoupled optical fiber would generate too much signal noise to be useful," she added in the report.
It should be noted that the approximation coefficient that determines the limitations level CL to one leads to the emergence of a large static error, which is especially evident in the presence of total signal noise.
There is lesser signal noise, which translates to lesser loss of audio data here, thus managing higher fidelity of audio through smartphones.
5) Apply thresholding to the obtained detail coefficients to suppress the signal noise.
In [13], the authors evaluate the performance of the CS based wideband radio receiver in both signal noise and processing noise environments, and some effective suggestions are given for the CS receiver evaluation.
Built-in filter reduces interference from electrical signal noise
It will feature speakers such as James White of Signal Noise and Marc Hemeon of Google presenting at the Argenta Community Theater during the day on Friday and Saturday, Aug.
Each input pin also has a glitch filter to protect against signal noise on the input pins.
WAGO Corporation's DIN-rail mount 288 Series Signal Noise Filter removes disturbances from incoming power for industrial control panels.
The I-PMD test analyzer can be placed anywhere in the network at any time and gathers data on PMD, in-band optical signal noise ratio and transmission problems.
Environmental factors such as temperature and humidity, or external parameters such as the signal noise in the power line, can be monitored to give an indication of how long a component has left before it will fail.
The isolation also breaks up ground loops and reduces signal noise that could interfere with measurement accuracy.
