Gen2nd:

-------------------------------------------------------------------------------
   Creates a second order transfer function

          s^2/wz^2 + 2 zz s/wz + 1
   K(s) = ------------------------
          s^2/wp^2 + 2 zp s/wp + 1

-------------------------------------------------------------------------------
   Form:
   [a, b, c, d] = Gen2nd( zz, wz, zp, wp, tSamp, sType )
-------------------------------------------------------------------------------
