- Improved on the filter circuit by using four of the same low pass filters with the same cutoff frequency of 14kHZ and cascading the output of one filter into the input of another filter, the system of low pass filters reduced the peak to peak voltage of the output signal of the system to less than 10 percent of the peak to peak of the input signal to the system. Also, tested the integration of the microphone, two 3.5mm breakouts, two-sided aux cable, aux to USB adapter, and laptop. The components were able to properly integrate and get sound from the mic onto the laptop.
- The schedule is on progress.
- Plans for the upcoming week is to now integrate the microphone with the filter circuit as an input and then integrate the output of the filter circuit with the other components like the laptop. Also, plan to work on the high pass filter part of the circuit.
