1. Write a MATLAB program code to implement the neural model shown in Figure (6). 2. Design the half adder circuit using ANN and then write it's a program code. 3. Design the SR flip-flop circuit using ANN and then write it's a program code. 4. Design 4*1 Demultiplexer circuits using ANN and then write it's a program code. 5. Design the JK flip-flop circuit using ANN and then write it's a program code. 6. Consider the neural network of McCulloch-Pitts neurons shown in the following Figure. Each neuron (other than the input neurons, N, and N) has a threshold of 2. a. Define the response of neuron Ns at time t in terms of the activations of the input neurons, N, and N, at the appropriate time. b. Show the activation of each neuron that results from an input signal of N1, N=0 at t = 0. 2 N3 Ns
