1-07-1982 | Monoflops are automatically associated with digital circuits, but there is no reason why they should not be used for analogue purposes. Obvi...

1-07-1982 | The term PDM merely stands for pulse duration modulation. A PDM amplifier consists of a pulse duration modulator, which converts an analogue...

1-07-1982 | 7-50 - elektor july/august 1982 Class A amplifiers are well-known in the audio world for their low distor- tion figures and big heat radiati...

1-07-1982 | Ordinary LEDs have a rather monot- onous diet: they will only "swallow" DC current with the right polarity, in which case a series resistor...

1-07-1982 | Nowadays, digital techniques are finding their way into more and more analogue circuits. Fortunately, this does not always call for the use...

1-07-1982 | 7-52 - elektor july/august 1982 Several relatively popular broadcasting stations can, in some areas, only be received on MW or LW. The repro...

1-07-1982 | The novel use of components in this electronic temperature indicator make it very simple and economical to build. It uses only three ICs, an...

1-07-1982 | The duty cycle of a square wave signal is normally measured by means of a pulse counter or an oscilloscope. However, this can be simplified...
