Тпп-160-70-уз.1 схема

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

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

Appropriate component-value substitutions will yield variations in these parameters. It detects if there is another telephone connected to the line, if there is a short or an open line. It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds.
