Save Nuttall defined four-term Blackman-Harris window object values in ASCII file
winwrite(H) opens a dialog to export the
values of the Nuttall defined four-term Blackman-Harris window object
an ASCII file. The file extension
.wf is automatically
winwrite(H,'filename') saves the values
of the Nuttall defined four-term Blackman-Harris window object
the current folder as a column vector in the ASCII file
The file extension
.wf is automatically appended
Generate two Nuttall-defined four-term Blackman-Harris windows:
The first window has N = 64 and is symmetric.
The second window has N = 63 and is periodic.
Display the two windows.
Hs = sigwin.nuttallwin(64); Hp = sigwin.nuttallwin(63); Hp.SamplingFlag = 'periodic'; wvt = wvtool(Hs,Hp); legend(wvt.CurrentAxes,'Symmetric','Periodic')
Generate a symmetric Nuttall-defined four-term Blackman-Harris window with N = 16. Return the window values as a column vector. Write the coefficients to an ASCII file in the current directory. Show information about the window object. Display the window.
H = sigwin.nuttallwin(16); win = generate(H)
win = 0.0004 0.0048 0.0306 0.1105 0.2778 0.5292 0.7983 0.9755 0.9755 0.7983
winwrite(H,'nuttallwin_16'); wininfo = info(H)
wininfo = 4×26 char array 'Nuttall Window ' '-------------- ' 'Length : 16 ' 'Sampling Flag : symmetric'
