1-06-2005 | Mobile telecom operators are rolling out the systems they hope will recover the billions invested in 3G licences for the new UMTS services....

1-06-2005 | The lack of availability of integrated modules in small quantities has until now been an obstacle to building a GPS receiver yourself. Now t...

1-06-2005 | This month look at current-carrying conductors. For example, two parallel running conductors carrying electrical currents of the same direct...

1-05-2005 | This month we present an extremely simple circuit. We operate a transistor as shown in the drawing and use a high-impedance voltmeter (any s...

1-04-2005 | This month we look at an everyday item: the humble coin, be it a 2-pound, or a 1- or 2-euro piece. Money, including coins, seems to have a s...

1-03-2005 | We have two audio amplifier design articles in this issue: one with valves and the other with transistors. They are just as different as peo...

1-03-2005 | Noise has a serious impact on the environment as well as on human beings. Besides classical sound reduction techniques such as insulation, r...

1-03-2005 | Modern circuits make ever more extensive use of FPGAs. Special software is required when designing with these devices. One of the companies...

1-03-2005 | This time we present yet another problem covering elementary circuit design. The schematic shows an opamp circuit supplying a rectangular vo...

1-02-2005 | Lamp intensity This time consider the circuit in Figure 1. Lamps La1 and La2 each have a nominal power P = 1 watt. Lamp La1 has an internal...
