1. What is the name of the model in figure below? a) Rosenblatt perceptron model
b) McCulloch-pitts model
c) Widrow’s Adaline model
d) None of the mentioned

Answer: b [Reason:] It is a general block diagram of McCulloch-pitts model of neuron.

2. What is nature of function F(x) in the figure?
a) linear
b) non-linear
c) can be either linear or non-linear
d) none of the mentioned

Answer: b [Reason:] In this function, the independent variable is an exponent in the equation hence non-linear.

3. What does the character ‘b’ represents in the above diagram?
a) bias
b) any constant value
c) a variable value
d) none of the mentioned

Answer: a [Reason:] More appropriate choice since bias is a constant fixed value for any circuit model.

4. If ‘b’ in the figure below is the bias, then what logic circuit does it represents? a) or gate
b) and gate
c) nor gate
d) nand gate

Answer: c [Reason:] Form the truth table of above figure by taking inputs as 0 or 1.

5. When both inputs are 1, what will be the output of the above figure?
a) 0
b) 1
c) either 0 or 1
d) z

Answer: a [Reason:] Check the truth table of nor gate.

6. When both inputs are different, what will be the output of the above figure?
a) 0
b) 1
c) either 0 or 1
d) z

Answer: a [Reason:] Check the truth table of nor gate.

7. Which of the following model has ability to learn?
a) pitts model
b) rosenblatt perceptron model
c) both rosenblatt and pitts model
d) neither rosenblatt nor pitts

Answer: b [Reason:] Weights are fixed in pitts model but adjustable in rosenblatt.

8. When both inputs are 1, what will be the output of the pitts model nand gate ?
a) 0
b) 1
c) either 0 or 1
d) z

Answer: a [Reason:] Check the truth table of simply a nand gate.

9. When both inputs are different, what will be the logical output of the figure of question 4?
a) 0
b) 1
c) either 0 or 1
d) z

Answer: a [Reason:] Check the truth table of nor gate.

10. Does McCulloch-pitts model have ability of learning?
a) yes
b) no
