| The present filter has an amplification ofx2, so that R5 and R6 in the feedback loop can be equivalent. In other words, their ratio is n...
| This tiny circuit can be used as a movement alarm in many situations: in a suitcase or on a bicycle to name but a few.
| The filter consists of two fourth -order sections in series. Various components in the second section have been given two different valu...
| As usual in RC filter designs. resistors R1-R4 and R5-R8 are given equal values. Unfortunately, again as usual. This leads to rather awk...
