The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband. It is also referred to as a maximally flat magnitude filter. It was first described in 1930 by the British engineer and physicist Stephen Butterworth in his paper entitled "On the Theory of Filter Amplifiers".

The b vector are the forward coefficients, e.g. the hamming window values in your example. The a vector are the feedback coefficients. If you set a to the scalar 1, it has no feedback and is an FIR. If it's a vector (usually starting with 1) then it's an IIR.
