Лира рп-249 электрическая схема


Телевидение Телефония Узлы цифровой электроники Фототехника Шпионская техника. Although originally designed for application in a communications system, the idea is readily adaptable for certain electronic music applications where waveform conversion is desired. This circuit converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies.

This is a rather sensitive circuit which will detect minute variations of a magnetic field, particularly the Earth magnetic field. Каталог программ Производители Каталог схем Datasheet catalog.

Лира рп-249 электрическая схема

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 converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies.

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. It detects if there is another telephone connected to the line, if there is a short or an open line.

Лира рп-249 электрическая схема

This circuit converts a square waveform to a triangle waveform while automatically maintaining a constant triangle amplitude for a wide range of input frequencies. 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.

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

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.
