(1) With signal impressed on the gate (Positive voltage),
FET gets short-circuited (a conducting wire of zero (0)
resistance); and
(2) With no signal impressed on the gate (GND), FET gets
open-circuited (a non-conducting wire of ∞ resistance).
(1) With no signal impressed on G1, FET1 gets
open-circuited, and with signal impressed on
G2, FET2 gets short-circuited, thereby causing
GND to be outputted to output terminals.
(2) With signal impressed on G1, FET1 gets short-
circuited, and with no signal impressed on G2,
FET2 gets open-circuited, thereby causing
180V to be outputted to output terminals.
