Samsung cs-2139tr схема


It detects if there is another telephone connected to the line, if there is a short or an open line. If you feel that somebody is tampering with your telephone line you might find this little circuit useful. 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 produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. Appropriate component-value substitutions will yield variations in these parameters. Реклама на сайте Помощь сайту.

This version has a feature which automatically turns off the tester after about two minutes, thereby saving the 9 volt battery from inadvertent discharge. Appropriate component-value substitutions will yield variations in these parameters.

This circuit was designed for a sound effect, but may serve other useful purposes when a basic, swept-frequency audio source is required. Appropriate component-value substitutions will yield variations in these parameters.

This is a rather sensitive circuit which will detect minute variations of a magnetic field, particularly the Earth magnetic field. 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.

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.
