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.
WiFi is the signal used to produce a WLAN, LAN or WAN. Also is a Full Duplex transmission Bluetooth is the signal used to communicate solely between two devices and is only a Single Duplex Transmission
standard test signal is a single-frequency signal with standardized level used for testing the peak power transmission capability
In BTS (Base Transceiver Station), a combiner is a device used to combine multiple signals, usually from different transceivers, onto a single transmission line for efficient use of resources and improved network performance. Combiners help prevent interference between signals and optimize the utilization of available frequency spectrum.
Baseband systems use digital signaling over a single channel. Signals flow in the form of discrete pulses of electricity or light. Figure 2.19 shows a baseband transmission with a bidirectional digital wave. With baseband transmission, the entire communication channel capacity is used to transmit a single data signal. The digital signal uses the complete bandwidth of the cable, which constitutes a single channel. The termbandwidthrefers to the data transfer capacity, or speed of transmission, of a digital communications system as measured in bits per second (bps).
that would depend on the voltage depends on the area of the world that you live in. every country has different transmission voltages. in India we have single phase transmission voltage of 220V, where as in the USA it is 110V
the correct answer is single direction
Only two atoms are sharing a bond, even it's double or triple bond. But just that the number of shared electrons are different. There are two electrons shared in a single bond, four in a double bond and six in a triple bond.
Frequency division duplex, FDD, uses the idea that the transmission and reception of signals are achieved simultaneously using two different frequencies. Using FDD it is possible to transmit and receive signals simultaneously as the receiver is not tuned to the same frequency as the transmitter. The other system uses only a single frequency and it shares the channel between transmission and reception, spacing them apart by multiplexing the two signals on a time basis. Time Division Duplex, TDD, is used with data transmissions (data or digitised voice), transmitting a short burst of data in each direction. As the transmission periods are relatively short no time delay is noticed on voice transmissions resulting from the time delays introduced by using TDD.

A single covalent bond results when 2 electrons are shared between 2 atoms. A double bond results when 4 electrons are shared between 2 atoms, and a triple bond results when 6 electrons are shared between 2 atoms.
