1-05-2016 | The specific feature of an inverted pendulum is that its center of gravity is higher than its rotational or pivoting axis. So it’s a pendulu...

1-09-2014 | The manual operation of the tap for a water filter is something that seems a suitable candidate for automation. This can avoid the unnecessa...

1-07-2011 | The aim of the present design is to create a filter that has less distortion at 20 kHz and which can cope with higher voltages, so that it a...

1-10-2008 | The instrument described in this article combines the functions of a sweep frequency generator (‘wobbulator’) and a spectrum analyser. In th...

1-07-2005 | The circuit shown here combines the functions of a low-pass filter and an integrator, presenting a novel approach to creating a precision 50...

1-07-2005 | Steep filters can be realised in many different ways, for example by connecting active 2nd to 5th-order sections in series and calculating t...

1-12-2004 | There are plenty of mains filters available, with or without sockets, with or without a switch, etc. In any case, this filter is very versat...

1-07-2002 | In the ‘Audio Limiter (for DVD)’ circuit, the peak values of the audio signals are used to reduce the dynamic range of the sound. A possible...
