Counters are available in two categories: ripple counters and.............. a. Binary counters O b. asynchronous counters O c. synchronous counters O d. None of the mentioned choices. Any half adder has number of inputs Select one: O a. 2 O b. 3 O c. borc O d. 1 The first step in designing E-3 code to BCD code convertor is a. obtain the simplified Boolean expression O b. derive the truth table O c. determine the number of inputs and number of outputs O d. draw the logic circuit If the least significant bit of any binary number is 1, then that number must be odd. Select one: O True False In the diagram shown in the figure, if you want to update the design to make the counter counts from O up to 31, what should you do? QA Count K J K J K Logic 1 O a. Change the type of flip flops to D-Flip flops O b. Add one more JK-Flip flop. O c. duplicate the number of flip flops d. Add two more JK-flip flops e. delete one flip flop
