using binary coded decimal {help please}

[ahmad murnai]

1. Find the truth table for output F5 in the circuit shown below, as a function of the three select inputs (S0, S1 and S2) where S2 is the MSB. thus, for each of eight rows, F5 will be equal to one of the D inputs..........<image address (http://alim.mediu.edu.my/pluginfile.php ... /ICMUX.png>



2. BCD numbers are applied sequentially to the BCD-to-decimal decoder in fig. draw a timing diagram, showing each output in the proper relationship with the others and with the inputs.

and given inputs as : A0. 000010001, A1. 001100110, A2. 010101010 A3. 100010000

decoder

3. Use 74HC195 4-bit shift registers to implement a 16-bit ring counter adn Show the connections. (use multimedia logic software as given in the lab)

I guess you are missing some diagrams here.
