<p>PURPOSE:To easily set information to show a start and a completion timing by issuing instruction to lead the information whose start timing is shown by the setting means of an electronic equipment such as a tape recorder, etc., by a prescribed time and to delay the set timing of the information whose completion timing is shown by the prescribed time. CONSTITUTION:An audio signal by external input from the input terminal of the electronic equipment is inputted to an A/D converter 10, and an inputted signal is converted to a digital signal, and it is inputted to a level detector 11 and a delay unit 12. The digital signal inputted to the delay unit 12 is delayed by a constant time (T1), and is sent to a signal processing part 13. And also, at the detector 11, it is detected whether the level of the signal is over or under a mean level based on the mean level of the digital signals as a high level or a low level, and a detected result is outputted to a microcomputer 14, and the set timing of the information is indicated to the processing part 13, then, the start timing is advanced by the prescribed time and the completion timing is delayed by the prescribed time.</p> |
