RJ-11 modular jack, RJ-11 modular jack on the wall, protector block on the outside of the house, to the lugs in the protector box were it terminates, the termination forms a bridge between the house and the outside plant telephone wire. A drop wire connects the block to the nearest telephone pole termination point. The main distribution frame at the central office which has a vertical side and a horizontal side. The termination from the outside plant is on the vertical side and the switch is connected to the horizontal side.
The microphone turns your voice into an electrical signal - which then travels down the wires to the destination phone - where it's turned back into sound again.
When you are stung by a bee you don't feel it until the impulse reaches your brain. The signal travels along your nerves to your spinal cord, where it is turned into a chemical message and sent to your brain.
light
A satellite signal will be a radio signal. And a radio signal in space travels at the speed of light.
When you decide to move, an electrical signal called an action potential is generated in your brain. This signal travels along your neurons and reaches the skeletal muscle cells via motor neurons. At the neuromuscular junction, a chemical called acetylcholine is released, which stimulates the muscle fibers to contract and initiate movement.
Typically, the electrical signal that travels from the dendrites across the cell body travels by cable conduction properties (like cable TV). Once the signal reaches the axon hillock, which is the spot where the axon branches off the cell body, the electrical signal starts traveling by action potentials (and maybe some cable conduction). The signal travels to the terminal end of the axon where it initiates a calcium influx, which in turn initiates a release of neurotransmitter to act on the next, post-synaptic neuron. The axon is the long process (arm) that extends from the first cell body to the next neuron.
It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.It means that, as the signal travels over the wire, it will (a) get weaker, and (b) the signal for the individual bits will "spread out" until they overlap with the neighboring bits.
A signal starts at point X. As it travels to point Y, it loses 10db. At point Y, the signal is boosted by 5db. As the signal travels to point Z, it loses 7db. What is the db strength of the signal at point Z?
boz there is lesas interferance to the signal as a signal travels...............
Digital
communication
Digital signal conversion is done on the telephone unit itself. Whether it is a call forwarding service or not.
