Hi there
This is what i am trying to get working but not succesfully. Can anyone help please.
We suppose to connect a circuit with use of TL071,2 op-amps (which will be powered by +-15V) to an i-pod or some similar mp3 player with output around 1V. Now the signal is amplified and then divided into bass, middle, treble using low, band and high pass filters to light up LED for each part of the frequency (0 - 100, 100 - 1000, 1000- ... Hz).

There are many schematic-drawing softwares but I use Microsoft Paint. I Copy and paste parts and pieces of datasheets and other schematics.
Here is the Bass Filter of your circuit:

I also chat on this website.
Your schematic and breadboard here show the trimpots P2 and p3 that were removed on the other websites. |
