pseudo vintage filter

  Hello English talking people,

just a few words to present my 'numeric filter'. This is an audio-frequency
two-voices active filter allowing to change the frequency cut-off with a
single potentiometer.

What you see is the frequency driver downstairs...and a filter upstairs
(waiting for time and money to make the second voice)

It could one of these things that nobody does anymore, just in case someone
dit it before...

Why ? Because all it contains is AOPs, logic circuits and TDA1022....so Jim
Morrison could have done it...(and I was not born)

Now my question could be: do we ear the phase of a signal as my system has
linear phase...cause I'm just wondering if my filter is just purely
unusefull...? But perharps you will appreciate the effort.

Best regards

Vincent Thiernesse
