Схема рассвет 40тб 301


This circuit was designed for a sound effect, but may serve other useful purposes when a basic, swept-frequency audio source is required. Каталог программ Производители Каталог схем Datasheet catalog. 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.

Although originally designed for application in a communications system, the idea is readily adaptable for certain electronic music applications where waveform conversion is desired. Телевидение Телефония Узлы цифровой электроники Фототехника Шпионская техника.

Схема рассвет 40тб 301

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.

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.

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