1-07-2001 | Anyone who has ever taken part in a listening test with various loudspeaker systems and amplifiers knows that the differences are often very...

1-07-2001 | Low-pass LC-filters in the audio frequency range require huge ferrite-cored inductors. Active filters are also tricky to construct because o...

1-07-2001 | A temperature measurement system with up to eight distributed temperature sensors can be realised using only a single signalling lead. This...

1-07-2001 | There are monitors which only have three BNC inputs and which use composite synchronisation (‘sync on green’). This circuit has been designe...

1-07-2001 | If you want to be independent of the local radio stations for testing VHF receivers, you need a frequency-modulated oscillator that covers t...

1-07-2001 | This circuit is a video line driver specifically intended for use with a single-ended power supply. As a matter of fact, the synchronised ou...

1-07-2001 | Everyone will be familiar with the problem of voltage drop across wires, connectors or filtering components such as inductors, which force t...

1-07-2001 | This circuit is designed to provide a wideband digital sine wave signal source. Its main feature is that because it synthesises the signal i...

1-07-2001 | In lighting controllers and clock circuits that need the mains frequency as a parameter for evaluations carried out within a microcontroller...

1-06-2001 | A few months ago under this heading, we presented a number of Internet addresses for MP3 projects. Most of them are based on re-using hardwa...
