i have to develope matlab program:
the formula for transition width is given in terms of r and s both.
the value of r varies from 2 to 128 and for EACH value of r , s is varies from r+4 to r+100.
the matlab program reads from lookup table the values of transition width for filters obtained for above mentioned values of r and s ... and finds minimum value of r and s for n= r+s-1.
