This formed a local circuit at the transmitting station.
In the second case, however, there are all the losses due to transmission from the central station to the train to be considered, as well as the cost of the transmitting apparatus itself.
Every part of a machine transmitting force suffers elastic defor mation, and the force may be measured indirectly by measuring the deformation.
This is a severe limitation to the use of telephone lines for transmitting data between computer systems.
The telautograph is on a similar principle to the Cowper apparatus, the motion of the transmitting pencil or stylus used in writing being resolved by a system of levers into two component rectilinear motions, which are used to control and vary the currents in two distinct electrical circuits.
