QUESTION i please help........

Question iii please help......

a) Convert the decimal number - 239 into a signed binary number using (1) sign-magnitude method (2) 1's complement method (3) 2's complement method b) If the above decimal number is positive , that is + 239, then convert it to a signed binary number using 1 's complement method c) Do the following binary subtraction: 101111111.01111- 001011010.10110 d)Explain Types of RAM?

1) Is it a Mealy machine or Moore machine? 2) Derive simplified expressions for Output z, and next state FF outputs y1+ and y2+ in terms of input w, and present state y1 and y2. Simplify using Boolean manipulation. You need not name specific Boolean properties/Theorems used. Leave final answers in simplest SoP/PoS forms. 3) Derive its encoded State-Transition Table. 4) Using the encoded State-Transition Table from part c, derive the symbolic state-transition table. Define your states. Use S0, S1, S2, and so on for state names. 5) Draw state diagram with all states and all transitions shown clearly. 6) What sequence of input values on wire w is detected by this circuit?

A multiplexer a. Selects where data should be sent b. Selects one out of several data input lines c. Has a single input and converts it to a binary output d. Has a binary input and converts it to a single output

PLEASE ANSWER ASAPP!!!!!!!!!!
