| This simple control circuit allows the level of an external stereo audio source to be adapted to the sensitivity of, for example, a sound ca...
| This circuit is intended as an extension for (pre-) amplifiers, to increase the number of inputs. Ever since the introduction of MD-recorder...
| This circuit arose from the need to couple the outputs of two CDROM drives to the input of a single sound card. Simply ‘stacking’ the connec...
| In the February 2002 issue of Elektor Electronics, we described an S/PDIF tester, consisting of a special decoder IC with integrated D/A con...
| This circuit, designed for audio applications, allows the user to select which input signal will be enabled when the system is switched on....
| Those of you who are lucky enough to possess a DVD player and have watched a movie with lots of special effects, will certainly have noticed...
| In the ‘Audio Limiter (for DVD)’ circuit, the peak values of the audio signals are used to reduce the dynamic range of the sound. A possible...
| This circuit can be included in every S/PDIF link between two digital audio devices (CD player, DVD player, CD recorder or MD recorder). Bes...
| Add two op-amps to a Wien-Robinson bridge and we can construct a notch filter whose centre frequency can be set using a single resistor. Thi...
