Hi Guys...i am building the circuit that i have supplied a link to but can't find any info about how it works, setting up or testing, so far i have built the input stage and the top filter (u1a and u1b) respectively, on feeding the input with a gorgeous sinewave, everything looks good untill the signal comes out of pin 9 where is is ringing badly? i don't know what to expect at the output, i am assuming that as the frequency changes, the voltage at the output rises and falls respectively as it does on mine, i expected a clean rising and falling D.C voltage at though instead of a peaky waveform at the Cathode of D1 though, can anyone give any insight to this circuit please?
I am aiming to be able to hook up my signal generator and sweep though 40Hz-16Khz and seeing the leds sweep through from bottom to top as the frequency rises.....or am i mistaken about what this circuit does?
