Ordinary crystal detectors cannot demodulate continuous waves; the direct current (DC) signal is inaudible in headphones.〔K. G. Beauchamp,''History of telegraphy'', IET, 2001 ISBN 0-85296-792-6, page 201 〕 One form of the tikker consisted of a fine wire resting on a rotating drum, which interrupted the DC voltage to produce an audible tone.〔 Popular Science Apr 1916 page 627〕 The tikker was invented in 1908 by Valdemar Poulsen and Peder Oluf Pedersen. Poulsen also experimented with using the tikker to send speech with spark gap transmitters such as the arc converter. 〔 Carroll W. Pursell, ''Technology in America: a history of individuals and ideas'', page 195〕 Poulsen is perhaps best known for developments in magnetic recording. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tikker」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
