Broadcasting and Television Media

As calculated previously, the carrier frequency is 2500 kHz. The next available channel for an AM station would be 2500 kHz + 250 kHz = 2750 kHz.

INSAT-1B was a major Indian communication satellite launched in 1983, which played a crucial role in expanding television broadcasting and telecommunications across India.

Hubble data was initially stored on the spacecraft in reel-to-reel tape recorders but these were replaced by solid state data storage facilities during serving missions 2 and 3A. Hubble transmits about 140 gigabits of raw science data every week.

Buckingham Canal is a long fresh water navigation canal. It is running parallel to the Coromandel Coast of South India from Kakinada in the East Godavari district of Andhra Pradesh to Villupuram District in Tamil Nadu. Its length is 796 kilometres. The canal was used to convey goods up and down the coast from Vijayawada to Chennai. But, this channel has lost its importance now. It was damaged due to the cyclones of 1965-1966 and 1976. It is little used and no longer well maintained. It is badly polluted from sewage and industrial effluents in Chennai.

This is a resonance in the circuit--- when you have a bunch of different

frequencies driving a resonant system, the response is only strong for

those frequencies which are close to the natural frequency of the

resonant oscillator. The frequency dependent amplification  is used to done through the resonance circuit for a desired frequency.

The most preferred mode of communication in Asia is Mobile communication.

Radio waves and microwaves propagate through space without the need for physical cables, making them a form of wireless communication.

GPS is not used for voice communication.

An early satellite-based system dubbed TRANSIT was up and running as early as 1960, with more refined and precise versions involving multiple satellites in general military use by the early 1980s (pictured, right). But it wasn't until 2000 that precision GPS navigation became open to the public.

The Global Positioning System (GPS) is a network of about 30 satellites orbiting the Earth at an altitude of 20,000 km. ... Once it has information on how far away at least three satellites are, your GPS receiver can pinpoint your location using a process called trilateration.

During Labor Day weekend in 1973, a meeting of about twelve military officers at the Pentagon discussed the creation of a Defense Navigation Satellite System (DNSS). It was at this meeting that the real synthesis that became GPS was created.

GPS (or global positioning system), is a satellite-based navigation system made up of a network of 24 satellites orbiting the earth at all times. This system, when the proper signals are received, allows a user to tell where they are located.

Dual tone multi frequency are not telephony services supported by GSM

DTMF ( Dual Tone Multiple Frequency ) is used to send to signals for button presses on telephones. The data is typically sent over voice channels and so in order to distinguish from human voice , when you hit a button the phone generates two tones of different frequencies - one lower frequency and one high frequency.

DTMF (dual tone multi frequency) is the signal to the phone company that you generate when you press an ordinary telephone's touch keys. In the United States and perhaps elsewhere, it's known as "Touchtone" phone (formerly a registered trademark of AT&T).

GSM is a globally accepted standard for digital cellular communications. GSM uses narrowband Time Division Multiple Access (TDMA) for providing voice and text based services over mobile phone networks.

Video text is a combination of Computer technology

An example of computer technology is the development of a software program that allows people to accomplish work at home which has been automatically assigned from computers at their job location. YourDictionary definition and usage example.

Technical terms are an essential part of all technical and scientific writing. Each field and specialty typically uses a vocabulary that relays a variety of specialized concepts by means of technical language.

An IT career involves installing, organizing and maintaining computer systems as well as designing and operating networks and databases. Computer science is focused entirely on efficiently programming computers using mathematical algorithms.

Telephone companies use FDM

Frequency-division multiplexing. In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal.

Frequency Division Multiplexing (FDM) is a networking technique in which multiple data signals are combined for simultaneous transmission via a shared communication medium. FDM uses a carrier signal at a discrete frequency for each data stream and then combines many modulated signals.

Fused deposition modeling (FDM) is an additive manufacturing (AM) technology commonly used for modeling, prototyping, and production applications as trademarked by Stratasys Inc.. It is one of the techniques used for 3D printing.

For separating channels in FDM, it is necessary to use  Bandpass filters

A bandpass filter is an electronic device or circuit that allows signals between two specific frequencies to pass, but that discriminates against signals at other frequencies. Unlike the low pass filter which only pass signals of a low frequency range or the high pass filter which pass signals of a higher frequency range, a Band Pass Filters passes signals within a certain “band” or “spread” of frequencies without distorting the input signal or introducing extra noise.

Frequency Division Multiplexing (FDM) Frequency-Division Multiplexing (FDM) is a scheme in which numerous signals are combined for transmission on a single communications line or channel. It is analog multiplexing technique. ... FDM multiplexing technique is based on orthogonality of sinusoids.

The modulation can be AM,SSB, FM or PM . The modulated signals are then added together to form a composite signal which is transmitted over a single channel . The spectrum of composite FDM signal has been shown in fig.1 . Generally, the FDM systems are used for multiplexing the analog signals .

For separating channels in TDM, it is necessary to use  Time slots.

Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern.

Time-division multiplexing (TDM) is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing.

Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern. It is used when the bit rate of the transmission medium exceeds that of the signal to be transmitted.
