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...
