1-07-1999 | The circuit shown in the diagram is intended for applications in which relatively large pulse-shaped signals are to be applied to a standa...

1-07-1999 | The title of this article naturally raises the question of why we think that the generous selection of fully integrated voltage regulators...

1-07-1999 | This design is complementary to the design described in the article ‘PAL timing (1)’, which also appears in this issue. It is intended to...

1-07-1999 | Although the oscillator in the diagram at first sight resembles a standard Wien bridge type, it is in fact a variant of it since it is tun...

1-07-1999 | Many modern circuits tend to work from a single supply voltage of 3 V. But often they need a virtual earth at half the supply voltage for...

1-07-1999 | The design of frequency and pulse doubling circuits is normally complex and critical. The circuit is a pleasant exception to this. It is b...

1-07-1999 | WARNING: do not use this transformer for mains isolating, because its insulation is not capable of handling this. It is intended to preven...

1-07-1999 | With the equipment that is found in the domestic or office environment, the distinction between the various disciplines is becoming increa...

1-07-1999 | The circuit in the diagram enables the digital audio output of, say, a compact-disc (CD) player to be linked to two different appliances s...

1-07-1999 | The simplest version of a constant-current source, which we often use for that reason, consists of only a FET with the source and gate c...
