1.07.1982 | This circuit may look familiar to many readers since it is one of the many variations of circuits on the 555 timer theme. This does not detr...

1.07.1982 | The circuit here extends the effec- tiveness of the simple push-to-make switch by enabling it to be used as either a "one-shot", with clean,...

1.07.1982 | 7-28 — elektor july/august 1982 A true RMS converter can be a very complex circuit requiring high tolerance components and precision calib...

1.07.1982 | H There are many ICs available today that contain all the circuitry required for various versions of power output stages. The IC presented...

1.07.1982 | If the voltage at the differential input of an OTA, such as the XR/LM 13600, is strongly positive or negative, the output current will equal...

1.07.1982 | 7-30 — elektor july/august 1982 The TRS 80 computer is a fairly good machine, but the cassette interface has already driven many an owner...

1.07.1982 | The majority of audio mixer circuits published to date in Elektor (and other magazines) require a relatively large number of components. How...

1.07.1982 | Depending on their condition 1.5 V batteries supply a voltage of 1.2 ... 1.7 V. This circuit can be very useful when a project has to be fed...

1.07.1982 | 7-32 — elektor july/august 1982 Normally, the high impedance input of the "front end" amplifier in a digital voltmeter is protected agains...

1.07.1982 | Thermistors and even light bulbs have often been used in oscillator circuits to stabilise the output amplitude. The resistance of such compo...
