| The manual operation of the tap for a water filter is something that seems a suitable candidate for automation. This can avoid the unnecessa...
| 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...
| The instrument described in this article combines the functions of a sweep frequency generator (‘wobbulator’) and a spectrum analyser. In th...
| The circuit shown here combines the functions of a low-pass filter and an integrator, presenting a novel approach to creating a precision 50...
| Steep filters can be realised in many different ways, for example by connecting active 2nd to 5th-order sections in series and calculating t...
| 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...
| 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...
| In communications receivers and microphone amplifiers for transmitting equipment, there is frequently a need for a narrow, low-frequency ban...
| This circuit is based on the configuration of a fifth-order Butterworth filter using only one opamp (see p 116 of the 1995 Summer Circuits i...
