stmcb Compute linear model using Steiglitz-McBride iteration Calling Sequence [b,a] = stmcb(h,nb,na) [b,a] = stmcb(y,x,nb,na) [b,a] = stmcb(h,nb,na,niter) [b,a] = stmcb(y,x,nb,na,niter) [b,a] = stmcb(h,nb,na,niter,ai) [b,a] = stmcb(y,x,nb,na,niter,ai) Parameters b,a : coefficients of the system function,nb is number of zeros and na is number of poles h : impulse response of the system x, y : input and output of same length given to the system nitren : number of iterations ai : initial estimate of the denominator coefficients Accepts only real i/ps, complex i/ps are not accepted due to limitations of the 'filter' function in Scilab Examples h = [0.0003 0.0033 0.0149 0.0432 0.0911 0.1493 0.1985 0.2190 0.2007 0.1479 0.0764 0.0070 -0.0429 -0.0649 -0.0601 -0.0375 -0.0092 0.0142 0.0265 0.0267 0.0180 0.0057 -0.0052 -0.0115 -0.0123 -0.0088 -0.0033 0.0018 0.0050 0.0057 0.0043 0.0018 -0.0006 -0.0021 -0.0026 -0.0021 -0.0010 0.0001 0.0009 0.0012 0.0010 0.0005 0.0000 -0.0004 -0.0005 -0.0005 -0.0003 -0.0000 0.0002 0.0002 0.0002 0.0001 0.0000 -0.0001 -0.0001 -0.0001 -0.0001 -0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 -0.0000 ] plot(h); //plotting required impulse response title "Required impulse respose (h) plot " xlabel "samples (n)" ylabel "magnitude {h(n)} "
