Схема телевизора brown


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. 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.

This version has a feature which automatically turns off the tester after about two minutes, thereby saving the 9 volt battery from inadvertent discharge. It detects if there is another telephone connected to the line, if there is a short or an open line. Телевидение Телефония Узлы цифровой электроники Фототехника Шпионская техника. Appropriate component-value substitutions will yield variations in these parameters.
