FIR approximation of raised cosine filter
rool-off factor
over sampling factor
number of coefficients of the FIR filter
y = rc_fir(r,osf,n) y = rc_fir(r,osf,n,'sum') Normalize the coefficients to have sum = 1 (default behavior) y = rc_fir(r,osf,n,'energy') Normalize the coefficients to preserve energy : <span><img src='./_LaTeX_rc_fir.xml_1.png' style='position:relative;top:21px;width:85px;height:42px'/></span>
