If you want to design counter that count from 0 to 7 , how many states we need to implement this counter using jk flip flops Select one: a. 8 b. 0 c. 7 d. 3 3. if you have the following function F{W,X,Y,Z)=m0+m1+m2+m3+m8+m9+m10+m11, the number of essential prime implicant is: Select one: a. 4 b. 3 c. 1 d. 2 4. If we have 3 bit input function, we can use the following MUXS to implement the function: Select one: a. 8 to 1 MUX b. 4 to 1 MUX AND INVERTER c. All the answers are correct 5. If you have 5 bit shift register (the current input is 10100 ) and the output of this shift register is connect to the input (feed back) of this shift register, in how many clock cycle needed to have on the input 10100 Select one: a. 5 b. 4 c. 1 d. 3 6. If you have 3 bit shift register(called A) and the output of this shift register is connected to input of a another 3 bit shift register(called B), how many clock cycles are needed to copy the A on B Select one: a. 3 b. 1 c. 2 d. 0 7. If you have the function F(A,B)=m1+m3, to implement this function we can use: Select one: a. 2 to 1MUX b. 4 to 1 MUX c. All the answers are correct
