Part B: Low-pass filter

Step 0
Background on the low-pass filter











Step 1

Build the low-pass filter circuit. Please download the wiring help app.


Please refer to the picture of the circuit above for additional help



Step 2
 
Frequency response: Please see the circuit simulation app for theoretical calculation, to be compared with experimental measurements. Below is an example: the results of the circuit in the photo.


Theory:  From circuit simulation app:
Bode magnitude                                                         Bode phase
  


Experiment: For the actual circuit in the photograph:
Bode magnitude                                                         Bode phase
 



Theory:
From circuit simulation app:



Experiment: For the actual circuit in the photograph:
Nyquist 2D                                                                           Nyquist 3D (white horizontal arrow is Log frequency)
 

Step 3
