Rolsen d15r22ntd схема


If you feel that somebody is tampering with your telephone line you might find this little circuit useful. It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. Реклама на сайте Помощь сайту. This circuit converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies. Телевидение Телефония Узлы цифровой электроники Фототехника Шпионская техника.

Among the essentials for circuit design and prototyping is the continuity tester, a simple device which provides an audible indication when a sufficiently low resistance is applied between its input probes.

If you feel that somebody is tampering with your telephone line you might find this little circuit useful.

This is a rather sensitive circuit which will detect minute variations of a magnetic field, particularly the Earth magnetic field. This circuit converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies. If you feel that somebody is tampering with your telephone line you might find this little circuit useful.

It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. 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.

Appropriate component-value substitutions will yield variations in these parameters. Каталог программ Производители Каталог схем Datasheet catalog.

This version has a feature which automatically turns off the tester after about two minutes, thereby saving the 9 volt battery from inadvertent discharge. It detects if there is another telephone connected to the line, if there is a short or an open line. Реклама на сайте Помощь сайту.
