Эл схема vestel vr54ts

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

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 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. 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. 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.
