Here the power-transmission ratio is Figure 5: Power-transmission ratios (Pr)
according to frequencies (f). Frequencies lying between 0 and U, fz and f3, etc.,
called pass bands, are totally transmitted. Frequencies between /, and f2, h and U
Various practical devices have to be incorporated in such a source to ensure
large output and to diminish the distortion due to the resonant or normal mode
frequencies of the cone. The efficiency of an electrodynamic loudspeaker tends
to vary ...
Such transitions can be either spontaneous or can be induced by the application
of appropriate external electric or magnetic fields at resonant frequencies.
Transitions also can occur in atoms, molecules, and ions between high-lying
