This promotes the horizontal frequency of the signal from 15. 734 kHz to 31. 47 kHz ( in the NTSC case, numbers for PAL are slightly lower ), which can be the used to drive a VGA monitor on an Amiga.

In addition, during this silent period all coastal and ship stations were required to monitor the frequency, listening for any distress signals.

There may be concerns about privacy since conversations may be picked up on a scanner, baby monitor, cordless phone, or a similar device on the same frequency.

In Canada Flight Information Centres ( FIC ) monitor the frequency 126. 7 MHz ( the common en route frequency for broadcasts and traffic information in Canada ) as well as 121. 5 MHz, the emergency frequency.

The controller sends a digital signal to all radios monitoring that talkgroup, instructing the radios to automatically switch to the frequency indicated by the system to monitor the transmission.

They use the standard CARS mandatory frequency of 122. 1 MHz and they also monitor the emergency frequency of 121. 5 MHz.

At minimum, controllers will monitor 2187. 5 kHz and 8414. 5 kHz and one more band.

Frequent users of TFT monitors usually are more sensitive to the low refresh rate of CRT monitors as the light behind a TFT monitor ( backlight ) usually is driven at 40 – 50 kHz, which is unnoticeable to the human eye.

The monitor supports 15 / 24 and 31 kHz with up to 65, 535 colors and functions as a cable-ready television ( NTSC-J standard ) with composite video input.

All large ships at sea had to monitor 500 kHz at all times, either with a licensed radio operator or with equipment that detected an automatic alarm signal.

The CARS also monitor the NDB which broadcasts the morse code identification " HI " on 361 kHz.

The monitor of this discourse grinned with pride and amusement as Helva's tone indicated pity for the unfortunate.

The DVG reads the commands and generates appropriate signals for the vector monitor.

A typical solution for malicious applets is to make the web browser to monitor applets ' activities.

In 1988 the release of the Amiga A2024 fixed-frequency monochrome monitor with built-in framebuffer and flicker fixer hardware provided the Amiga with a choice of high-resolution graphic modes ( 1024 × 800 for NTSC and 1024 × 1024 for PAL ).

* I / O ports: Expansion port, tape recorder connector ( 1200 baud variation on the Kansas City standard for data encoding ), aerial TV connector ( RF modulator ), composite video and RGB monitor output

The comparatively low price for a complete computer system with dedicated monitor, its high resolution monochrome text and graphic capabilities and the possibility to run CP / M software also rendered the system attractive for business users, which was reflected by a wide selection of application software.

The brainfuck language uses a simple machine model consisting of the program and instruction pointer, as well as an array of at least 30, 000 byte cells initialized to zero ; a movable data pointer ( initialized to point to the leftmost byte of the array ); and two streams of bytes for input and output ( most often connected to a keyboard and a monitor respectively, and using the ASCII character encoding ).

; Holter monitor: Portable ECG device for continuous monitoring.

Many countries such as the United States will monitor and control the banking sector through different agencies and for different purposes, although there is usually significant cooperation between the agencies.

NICU standard practice is to electronically monitor the heart and lungs for this reason.

They found that the key is for software to monitor the number of scans that machines on a network sends out.

The area of study examines issues such as how each major form of business entity may be formed, operated, and dissolved ; the degree to which limited liability protects investors ; the extent to which a business can be held liable for the acts of an agent of the business ; the relative advantages and disadvantages of different types of business organizations, and the structures established by governments to monitor the buying and selling of ownership interests in large corporations.

Peddle packaged his single-board computer design in a metal case, along with a full-travel QWERTY keyboard, monochrome monitor, and tape recorder for program and data storage, to produce the Commodore PET ( Personal Electronic Transactor ).

A monitor or display ( also called screen or visual display unit ) is an electronic visual display for computers.

The estimation of the monitor size by the distance between opposite corners does not take into account the display aspect ratio, so that for example a 16: 9 widescreen display has less area, than a 4: 3 screen.

: This term is used both for conventional p – n diodes used to monitor temperature due to their varying forward voltage with temperature, and for Peltier heat pumps for thermoelectric heating and cooling .. Peltier heat pumps may be made from semiconductor, though they do not have any rectifying junctions, they use the differing behaviour of charge carriers in N and P type semiconductor to move heat.

An unusual feature was a monitor port for connection of a computer monitor, as an alternative to the TV output.

Popular electronics include: electronic sound modules ; laptop computers used to activate loops, sequences and samples ; metronomes and tempo meters ; recording devices ; and personal sound reinforcement equipment ( e. g., a small PA system to amplify electronic drums and provide a monitor for singing ).
