Радиотехника 7210 схема


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

Appropriate component-value substitutions will yield variations in these parameters. 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.
