- Built a passive low pass circuit, using a resistor and capacitor from the lab. Also, calculated the capacitor and resistor values for the high pass filter. The goal is a filter that allows frequencies between 40Hz – 14Hz, so picking the proper resistors and capacitors an important. Currently, there is a 4-kiloohm resistor and 1 microFarad capacitor for the low pass filter and a 10-ohm resistor and 1 microFarad. Also, parts were picked up and moved into the lab.
- The schedule is on progress
- Plans for the upcoming week is to implement the high pass filter. Also, test that the low pass and high pass filter works for the proper frequency range using the lab oscilloscope, and then start the process of connecting the microphone to the circuit.
