Here the absent sitter makes a `` date '' with a communicator ( someone close to him who is deceased ), asking him to `` come in '' at a certain hour, when a channel will be open for him.

The fact that in equivalent baseband models of communication systems, the signal spectrum consists of both negative and positive frequencies, can lead to confusion about bandwidth, since they are sometimes referred to only by the positive half, and one will occasionally see expressions such as, where is the total bandwidth ( i. e. the maximum passband bandwidth of the carrier-modulated RF signal and the minimum passband bandwidth of the physical passband channel ), and is the positive bandwidth ( the baseband bandwidth of the equivalent channel model ).

During a major news event one or more of the main news presenters may be sent to present live for the channel from the scene of the story, where they will conduct interviews with the people involved, question correspondents, introduce related reports and also give general information on the story, much as a reporter sent to cover a story would.

In fippled or ducted flutes, a precisely formed and placed windway will compress and channel the air to the labium ramp edge across the open window.

Further gate-to-source voltage increase will attract even more electrons towards the gate which are able to create a conductive channel from source to drain ; this process is called inversion.

For either enhancement-or depletion-mode devices, at drain-to-source voltages much less than gate-to-source voltages, changing the gate voltage will alter the channel resistance, and drain current will be proportional to drain voltage ( referenced to source voltage ).

We will consider to be an inherent fixed property of our communications channel ( representing the nature of the noise of our channel ).

Devices set to a specific channel will ignore the messages sent on all other channels.

This dredged channel in the North Sea is being widened to to facilitate the largest container vessels for the new Maasvlakte 2 that will be opened in 2012.

This will read data from channels c1 or c2 ( whichever is ready ) and pass it into a merged channel.

If countN reaches 100, reads from the corresponding channel will be disabled.

This means the user has only to program the set-top box and it will switch to the right channel at the right time and " wake up " the VCR or DVR to record, so there is no need for a timer.

In a simplistic approach, channel efficiency can be equal to channel utilization assuming that acknowledge packets are zero-length and that the communications provider will not see any bandwidth relative to retransmissions or headers.

The building will also contain an integrated newsroom used by the international World Service, the international television channel BBC World News, the domestic television and radio BBC News bulletins, the BBC News Channel and the local news for the BBC London region on television and radio.

The stored data can be used to maximize the chance that the best channel to link with a given partner will be chosen first.

Like analog modems, DSL transceivers constantly monitor the quality of each channel and will add or remove them from service depending on whether they are usable.

A channel will appear in the low group for one repeater section and will then be translated to the high group for the next section because of frequency frogging.

If the channel is clean enough, most of the time only one bit will change in each triple.

When a message is transmitted through such a channel, the spread pulse of each individual symbol will interfere with following symbols.

At the receiver, due to the presence of the multiple electromagnetic paths, more than one pulse will be received ( we suppose here that the channel has infinite bandwidth, thus the pulse shape is not modified at all ), and each one of them will arrive at different times.

A graphics relaunch in January 2007 saw the channel updated, with redesigned headline straplines, a redesigned ' Digital on-screen graphic ' and repositioned clock.

Philip Hayton and Anna Jones were the first two presenters on the set, the relaunch of which had been put back a week due to previous power disruptions at Television Centre where the channel is based.

NBC will relaunch msnbc. com and give the cable channel its own website in 2013.

Since 2005, with the relaunch of the TV channel, a greater emphasis has been placed upon interactivity.

The channel was intended to relaunch at a later date.

On 7 April 2011, Network Ten announced it would relaunch its sports based channel One, with general entertainment programming taking over its schedule from 8 May.

Since its relaunch in 2007, the channel has had various well-known people in and out of the soccer world do promos.

From the February 2004 relaunch, the channel came into its own.

Eventually, all live programming with the exception of Personal fX was dropped and the channel focused entirely on its classic television shows until its relaunch in mid-1997.

In 1996, MTV flew down Guns N ' Roses guitarist Slash to play on stage with Indus Creed at the channel ’ s relaunch as MTV India in Bangalore, India.

MadVision then came to terms with Viacom-owned Black Entertainment Television to relaunch the Soul Train Music Awards for BET's new spin-off channel, Centric, in November 2009, a move that may be one step into reviving the program.

The channel launched as talktv in 2000, but was not as widely available prior to its relaunch as MTV in March 2006.

In fact many analogue cable viewers that never had access to talktv were able to view the channel at, or soon after, its relaunch.

The name " Film4 Productions " was introduced in 2006 to tie in with the relaunch of the FilmFour broadcast channel as Film4.

Following the successful relaunch and rebranding of the channel UKTV G2 as Dave, the remainder of the UKTV network underwent the same treatment.

At the time of the Dave relaunch, UKTV Bright Ideas closed, freeing up the space to allow UKTV G2 + 1 to expand its hours to follow those of the parent channel fully ; due to the main channel's relaunch as Dave, UKTV G2 + 1 became Dave + 1.

The channel was receiving consistent poor ratings, and the BBC decided to relaunch the channel.

In October 2008, Corus announced it would relaunch CLT as Viva, a female-focused entertainment and lifestyle channel targeting the baby boomer demographic.

Plans to relaunch the channel as Slice were announced in November 2006 by Alliance Atlantis Communications.

From the station's relaunch as WEWB until December 2006, master control of the channel was located at sister station WB affiliate WLVI-TV in Boston.

The channel will close down on 8 October 2012 and will relaunch as D8 due to its purchase form Canal Group.

Following several on-air creative rebrands, and a repositioning to being a full drama channel, dropping much of its talk programming in recent years, W will now relaunch as SoHo, a brand that launched in New Zealand earlier this year, on Monday 20 August 2012 at 8: 30pm.
