1-07-1995 | A Bessel filter has a fairly constant transit time (delay) over the pass band, but its amplitude characteristic starts to fall off rather...

1-07-1995 | A small quartz clock that is powered by a 1.5 V battery provides a simple means of determining the capacity of a NiCd battery. The circui...

1-07-1995 | The Linkwitz-Riley crossover network is known for its homogenous performance and constant amplitude. The transfer is identical to that of...

1-07-1995 | Even with a good frequency meter, it is well-rugh impossible to set two frequencies to a fraction of a hertz. It can, however, be done w...

1-07-1995 | Push-pull oscillators have an important advantage over conventional oscillators: they provide appreciably more power at the same supply v...

1-07-1995 | The audio amplifier in a battery-operated scanner or walkie-talkie is often on standby for long periods. Of course, in that state it draw...

1-07-1995 | Since Ferranti have taken their well-known ZN436, a 6-bit digital to-analogue converter, out of production, the ZN426 has 'replaced' it....
