| If analogue signals have to be switched, a bilateral switch such as the 4066 is often utilised. Because this IC can be powered from single-e...
| This circuit has been designed to respond only to two hand claps which occur in (relatively) quick succession, and to ignore one hand clap o...
| One of the most frequent uses of n-channel MOSFET’s is as a voltage controlled switch. To ensure that the MOSFET delivers the full supply vo...
| There are presently many switching regulator ICs. However, the STA801 and STA802 provide two switching regulators in a single package, each...
| Unplugging or re-connecting equipment to the serial COM or PS2 connector always gives problems if the PC is running. Even if you only need t...
| Nowadays, there is a whole series of switching regulator ICs that work according to the step-up principle and thus convert the input voltage...
| The switching clock described here can control up to 16 channels and has 20 memories for individual switching times, each of which may apply...
| This time we’ll look at a kit for a remote control that allows you to send ten digital control signals over a distance of more than 50 metre...
| Specifications for receiver frontends, converters and detectors are generally very demanding. On the one hand they need to have high sensiti...
