VHDL program
Entity jk is
port(j:in std_logic;
k:in std_logic;
Q:out std_logic;
Qbar:out std_logic;
clk:in std_logic);
Don't specify feedback Q and Qbar as input in Architecture behavioral SO Answer is 3

Based on IC design inputs : j, k, clock, clear, preset) (i.e 5 inputs).
Generally we will consider 3 input (j, k, clock) or 4 inputs (j, k, clock, clear).

I think that five inputs are j, k, clk, preset, clear in VHDL.

VHDL is the hardware description language used in electronic design automation to describe digital and mixed-signal systems.

Answer is rite. One input is j, then k, other from output of Q to j then from Q', last one is clk.

J K flip flop takes past output as input. So Q and Q' is also a input counting to total 5.

In VHDL program we draw j, not (j) , k, not (k) and clk signal totallly 5 input signals.

I think it is because they will consider two inputs of Asynchronous JK FF as well.

But they ask question for input not output then how the answer is 5?

How 5? Ans should be 3. J, k and clk.
