Схема daewoo acd-7310


If you feel that somebody is tampering with your telephone line you might find this little circuit useful. Телевидение Телефония Узлы цифровой электроники Фототехника Шпионская техника. This circuit converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies.

Although originally designed for application in a communications system, the idea is readily adaptable for certain electronic music applications where waveform conversion is desired. It detects if there is another telephone connected to the line, if there is a short or an open line. This version has a feature which automatically turns off the tester after about two minutes, thereby saving the 9 volt battery from inadvertent discharge.

This circuit was designed for a sound effect, but may serve other useful purposes when a basic, swept-frequency audio source is required. It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. This version has a feature which automatically turns off the tester after about two minutes, thereby saving the 9 volt battery from inadvertent discharge.

If you feel that somebody is tampering with your telephone line you might find this little circuit useful. Appropriate component-value substitutions will yield variations in these parameters. This circuit converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies.

It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. This is a rather sensitive circuit which will detect minute variations of a magnetic field, particularly the Earth magnetic field.
