What uses TDM over two wires to divide a single channel into multiple channels?
T- Carrier
What is carrier telephony and Features of Carrier Telephone systems?
Carriers are the companies that construct and maintain the networks that provide telephone services. Carrier telephony is a method of transmitting several telephone channels over a single pair of wires. It was used extensively throughout the world in the 1940s through 1980s prior to the introduction of digital transmission systems. Carrier telephony systems ranged from single channel systems that transmitted one carrier channel on top of a normal voice frequency channel to co-axial cable systems that had thousands of channels. It was mostly used to provide trunk lines between cities although subscriber carrier systems did exist.

What are advantages of FM transmissions?
In FM, within small range of tuning, we can access multiple channel. We can access single channel in 0.5 MHz. Range of FM can go to several miles. FM needs comparatively less power.
Am single-sideband full carrier?

What carrier is pinger textfree I want to connect with facebook to get facebook texts and it needs a carrier what carrier would it be?
there isnt one single carrier....pinger supports all US carriers....
Difeerence between n-channel and p-channel fet?
The field-effect transistor (FET) is a transistor that relies on an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. FETs are sometimes called unipolar transistors to contrast their single-carrier-type operation with the dual-carrier-type operation of bipolar (junction) transistors (BJT). The concept of the FET predates the BJT, though it was not physically implemented until after BJTs due to the limitations of semiconductor materials and the relative ease of manufacturing BJTs compared to FETs at the time.
Advantage and Disadvantage of OFDM?
ADVANTAGES:Makes efficient use of the spectrum by allowing overlap.By dividing the channel into narrowband flat fading subchannels, OFDM is more resistantto frequency selective fading than single carrier systems are. Eliminates ISI and IFI through use of a cyclic prefix.Using adequate channel coding and interleaving one can recover symbols lost due to thefrequency selectivity of the channel. Channel equalization becomes simpler than by using adaptive equalization techniques withsingle carrier systems. It is possible to use maximum likelihood decoding with reasonable complexity.OFDM is computationally efficient by using FFT techniques to implement the modulationand demodulation functions. Is less sensitive to sample timing offsets than single carrier systems are.Provides good protection against cochannel interference and impulsive parasitic noise.DISADVANTAGES : The OFDM signal has a noise like amplitude with a very large dynamic range, therefore itrequires RF power amplifiers with a high peak to average power ratio. It is more sensitive to carrier frequency offset and drift than single carrier systems are dueto leakage of the DFT.
Is Jason Kennedy from the e channel single?
I heard he was single
What are the basic characteristics of time division multiple access?
Shares single carrier frequency with multiple usersNon-continuous transmission makes handoff simplerSlots can be assigned on demand in dynamic TDMALess stringent power control than cdmadue to reduced intra cell interferenceHigher synchronization overhead than CDMAAdvanced equalizationmay be necessary for high data rates if the channel is "frequency selective" and creates intersymbol-interferencecell-breathing-telephony(borrowing resources from adjacent cells) is more complicated than in CDMAFrequency/slot allocation complexityPulsating power envelope: emiwith other devices
