The blackmann(N) command returns a ___________(a) N-point periodic bla

1.	The blackmann(N) command returns a ___________(a) N-point periodic blackmann window(b) N+1-point periodic blackmann window(c) N+1-point periodic blackmann window(d) N-point symmetric blackmann windowThis question was posed to me in final exam.Asked question is from Fourier Analysis and Filtering in section Beyond the Basics of MATLAB
Answer» Right answer is (d) N-point symmetric blackmann window The best I can EXPLAIN: Unless mentioned, the default type of blackmann window GENERATED by the blackmann() COMMAND is a symmetric ONE. It is an N-point symmetric blackmann window and hence the REST of the options are incorrect.
