This lesson will teach you how to use the scipy.signal.remez function to design linear phase FIR filters with specified pass band and stop band gains. The Example_FIR_Filter_Design.ipynb notebook has all the entries provided to design a filter meeting the given specifications. In the FIR_Filter_Design_Problem.ipynb notebook you will enter values to design a set of filters that are used as a simple three-band equalizer. The Solution_FIR_Filter_Design_Problem.ipynb notebook contains one particular solution that meets the specifications.
