What reading level is Principles of Radiotelegraphy book?
To quickly assess the difficulty of the text, read a short excerpt:
Since no RADIOCIRCUITS 149 energy can be transmitted without a reaction, the resulting reaction damps or decreases the amplitudes of the oscillations. This damping is especially pronounced if the circuits are tuned. Of the energy that is transmitted to the secondary, part is con- verted into heat, part is radiated as electromagnetic waves, and part is returned to the primary circuit. In radiotelegraphy it is important to reduce to a minimum the part wasted as heat, and the part returned to the ...primary. The part radiated as electro- magnetic waves should be as great a per cent, as possible of the energy transmitted to the secondary circuit.
If the circuits are closely coupled the reaction of the primary is so active that much of the energy is returned to it. The in- Secondary Circuit FIG. 91. Damped primary and secondary currents.
terchange of the energy between the primary and secondary is illustrated in Fig. 90. An examination of the curves shows that the current in the primary dies out as that in the secondary increases, and vice versa.
