This week I made significant progress on the electronics. The filter board has been completely tested and is ready for integration into the synth. I built a testbench using an STM32 and I2S DAC to drive signals into the analog board for testing purposes:<\/p>\n

\"\"<\/p>\n

I was able to measure noise, channel matching, filter cutoff performance, and total harmonic distortion.<\/p>\n

Here’s a test with triangle wave input. The first image is input, second is low pass filtered (higher harmonics removed), and third is with 60dB resonance (higher harmonics and resonance added back.)<\/p>\n

In the final week, I will integrate this with the rest of the synth and connect it to our final microcontroller choice (Teensy 4.1). The main deliverable this week is oscillator code written in C to drive this board and also verify functionality after it’s completely integrated. We are still about a week behind in schedule, but given that we have no classes this week will still be able to get everything done.<\/p>\n","protected":false},"excerpt":{"rendered":"
