The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
They can be interfered by other transmission signals
Microwave transmission works by means of transmitting signals. This is used for television sets and communication systems. Signals are transmitted via satellites.
the part that facilitates the the transmission of signals is collectively known as the axon but more peculiarly known as the nerve endings.
In asynchronous transmission , the receiver and the transmitter each use their own clock signals so its not possible to know when a word starts and stops. while in synchronous , the receiver and the transmission have common clock signals.
The most common mode of transmission of TV signals are digital satellite and cable. New technologies allow transmission of signals by digital terrestrial TV, using aerial broadcasts to a conventional antenna. This provides a greater number of channels and a better picture and sound quality.
Actually you have this backwards, the telephone lines can only carry analogue signals (voice band, 20Hz to 3KHz) not digital signals.The device that converts digital signals to analogue signals for transmission over telephone lines is called a phone MoDem(this stands for phone modulator demodulator). At the opposite end of the line it of course converts the telephone analogue signals back to digital signals.
In Data transmission two types of transmission methods are available. One was ANALOGUE data transmission and DIGITAL data transmission.IN analog data transmission the data will be transmitted in analog signals like sinusoidal waveforms. But IN digital data transmission method the data will be transmitted in digital signals like square pulse's (in binary values).
They can be trasmitted
Radio signals travel at the speed of light
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing
Channel impairment in signals transmission: Noise, fading and distortion etc. that result in transmission quality degradations.
this is baseband transmission...
A multiplexor is used to encode multiple input signals for transmission over a single channel. This works because the bandwidth of the output channel is higher than the bandwidth of the input signals, allowing the input signals to share the output channel. At the other end, a de-multiplexor decodes the channel and decodes the individual input signals.
emf? (electromagnetic field interference)
mainly it is used in transmission and reception of TV signals
Microwave transmission is a technology used to transfer signals over a microwave link. http://en.wikipedia.org/wiki/Microwave_transmission
Transmission channels are defined as paths through which electrical signals can pass through. It may be in form of a physical cable.
High range of frequency that carries the message signals in transmission of data.after receiving the signals, the detector seperate the message and carrier .
Transmission lines are thicker than TV cable wires because the transmission lines are used to transmit both low freq and high freq signals. And the losses of the transmission lines depend the resistance of the line which inturn depend upon length and area. As we have to transmitt the signals over long distances the transmission lines are thicker in size.Whereas in TV cable wires the construction is totally different in which transmission of signals is in between two conductors thereby avoiding losses.Therefore there is no necessity for these lines to be made thicker. That is why transmission lines are thicker than TV cable wires.
