I really don't understand how to find the truth table of pass-transistor circuits. Pic related for example acts as an AND gate, but I keep feeling I analyze these kinds of circuits incorrectly, and I don't really get how you can tell that Vgs is definitely higher or lower than Vth, which determines whether or not current is flowing.
In the pic Vdd = 3.3V which is a logic 1 and 0V is a logic 0, while Vth = 1V.
