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
