The butter() command takes in ________(a) Stopband attenuation(b) Orde

1.	The butter() command takes in ________(a) Stopband attenuation(b) Order of the filter(c) Ripple frequency(d) NothingI had been asked this question at a job interview.This interesting question is from Fourier Analysis and Filtering in chapter Beyond the Basics of MATLAB
Answer» Right choice is (b) Order of the FILTER The best I can explain: The BUTTER command is used to generate the filter co-efficient of a Butterworth filter. This is done by giving the order of the filter and the cut-off frequency as input to the butter filter. The RIPPLE frequency and the stopband attenuation is given to the buttord() FUNCTION.
