Problem 1: Discuss the working of 4 x 1 multiplexer and 1 x 4 de-multiplexer with its logical diagram. Also Implement the function f (X, Y, Z) = ∑m (0, 2, 6, 7)

Problem 2: With the help of neat sketch, discuss the working of 4 x 2 Encoder and 2 x 4 decoder. Also implement the circuit with a decoder and external gates.

F₁ (A, B, C) = ∑m(1, 3, 4); F₂ (A, B, C) = ∑m(0,2,6,7)         

Problem 3: State the difference between the following

a) Combinational and sequential Circuit

b) RAM and ROM

Problem 4: State the difference between Characteristic table and excitation table. Also Illustrate the Characteristic and excitation table of SR, JK, D and T FF.     

Can you think of a new way to collect consumer data that will give CPG companies the information they need to improve products and services, but at the same time, deliver real benefits to consumers?

1. Explain your idea in terms of who the consumer is and what type of data will be gathered.
2. How will the data be gathered? 
3. How can the CPG brand use the data that is gathered?
4. What is the reward/benefit for the consumers sharing their data?
5. List 1-2 CPG brands that are currently doing a good job of collecting and rewarding for consumer data. How do they do it?
