The handsome young Emperor Alexander, in the uniform of the Horse Guards, wearing a cocked hat with its peaks front and back, with his pleasant face and resonant though not loud voice, attracted everyone's attention.
There was a rich, deep-toned, resonant eloquence mingled with the speculative exposition; his style of expression was clear, elegant and forcible, abounding in happy turns and striking antitheses.
At a later date a syntonic system comprising, as above stated, an antenna directly coupled to a resonant closed circuit was put into operation by Lodge and Muirhead, and much the same methods have been followed in the system known as the Telefunken system employed in Germany.
Antenna has several important parameters: resonant frequency,gain, impedance, aperture or radiation pattern, efficiency and bandwidth, polarization.
His commanding presence, mastery of diction, and resonant voice made him an effective platform speaker.
