1-12-2002 | The Manchester or biphase code is used very frequently, (examples include hard disk drives and networks), because the code contains both the...

1-12-2002 | Many designs call for a window comparator to determine if a voltage level falls within two voltage thresholds. Linear Technology has produce...

1-12-2002 | Generating digital square-wave signals at logic levels from fast signals having frequencies up to 150 MHz (such as sinusoidal signals from q...

1-12-2002 | A commonly encountered problem is that the code sent by an infrared transmitter cannot be evaluated by a microcontroller directly on being r...

1-12-2002 | The LT1970 from Linear Technology (www.linear-tech.com/pdf/1970f.pdf) is a power opamp with adjustable current limit, available in a 20 pin...

1-12-2002 | Bistable relays are particularly useful in applications where very low power consumption is important. This is because they only use a littl...

1-12-2002 | Slide scanners are available in all sorts and sizes, but if you want a reasonable level of quality they are rather expensive. Besides that,...

1-12-2002 | The circuit diagram shows a switched-capacitor voltage inverter with +5-V input and –3-V output, along with a supplementary cascade stage to...

1-12-2002 | There’s nothing new about a current source consisting of a transistor, a resistor and an LED to provide the reference voltage. However, what...

1-07-2002 | The joysticks used in games and modelling contain two potentiometers with a resistance of about 100 k?, which turn through 60 to 90 degrees....
