- Spent time testing the filter circuit. After testing founding that the filter was starting to cut off around 60kHz, but the desire is to cut off at 14kHz. Started to build the same resistor and capacitor configuration as the current low pass filter. The plan is that with multiple low pass filters with the same configuration, the output of one low pass filter can be feed into the input of another low pass filter in order to achieve the desired frequency cut off.
- The progress is still on schedule
- The plan for the coming week is to continue working on the filters and solder the other 3.5mm jack breakout. Also, connect the mic, the two breakouts, the 2 sided cable, the 3.5mm jack to the usb converter, and the laptop just to see if the parts allow the mic to properly connect to the laptop
