Panasonic sa-pm28 схема


It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. 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. 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. This circuit was designed for a sound effect, but may serve other useful purposes when a basic, swept-frequency audio source is required. Although originally designed for application in a communications system, the idea is readily adaptable for certain electronic music applications where waveform conversion is desired.

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

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.
