By performing cascading and / or summing / differencing operations using transfer function blocks G 1 (s) and G 2 (s), one CANNOT realize a transfer function of the form

G_{1} (s) (\frac{1}{G_{1} (s) } + G_{2} (s) )

G_{1} (s) (\frac{1}{G_{1} (s) }−G_{2} (s) )

By performing cascading and / or summing / differencing operations using transfer function blocks G₁ (s) and G₂(s), one CANNOT realize a transfer function of the form

$G_{1} (s) G_{2} (s)$
$\;{G_{1}\;(s)\;}/{G_{2} (s) }$
$G_{1} (s) (\;{1}/{G_{1} (s) } + G_{2} (s) )$
$G_{1} (s) (\;{1}/{G_{1} (s) }−G_{2} (s) )$
