Let me take a step back - the current schematic is not MCU based, let's say it's analog. The building blocks are: input amp -> bandpass filter -> lin-to-log converter -> AC-to-DC converter -> driver
The LPF is between the AC-to-DC converter and the driver. At that point, the audio signal has been already filtered, so in theory I should have only the "DC" component of a specific channel/audio frequency. Does it make more sense now? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
