Editor’s Note: This unusual circuit could be placed in the PLL/FLL family, but it’s neither. At its heart, it’s a self-adjusting monostable that will convert digital signals over a 5:1 frequency range ...

Active filters and advanced signal processing techniques are at the forefront of modern electronic system design, enabling precise manipulation of analogue signals for a variety of applications. Owing ...

Many analog signal-chain circuits require ac-coupling to eliminate unwanted dc voltages or offsets. The simplest means to ac-couple is to use a capacitor in series with the signal path, thus forming a ...

Many engineers who use spectrum analyzers on a regular basis might be content to know that their instruments will produce a display of “power versus frequency” with little idea of what’s going on ...
