Digital Logic Design Interview Questions & Answers
The actual number of flipflops required is equal to the ceiling of the logbase2 of the number of states in the FSM. For a state machine with states, a binary FSM only requires 4 flipflops while a onehot FSM requires a flipflop for each state in the design FPGA vendors frequently recommend using a onehot state encoding style because flipflops are plentiful in an FPGA and the combinational logic required to implement a onehot FSM design is typically smaller than most binary encoding styles.

As we know, rectifiers are primarily used to convert alternating current AC to direct current DC. There we find a considerable AC component in the output, which is called ripple. Many electronic systems require pure direct current supply to drive or power them. To make a efficient continuous power supply that gives pure DC output, we need to remove the AC component from the output of rectifiers. All flip-flops are set with data.

Now that we've cleared up what the scenario is, I'll give you an answer. Your circuit should produce the correct output. It uses more gates than needed, though, and is overly complicated. Specifically, the way you carry the result from the previous test into the next test is strange. You can add the circuit diagram directly into the question using the schematic editor. The schematic editor also includes a simulator so that you can test your ciruit directly. Suggestions in response to comments: You are using the output from the first test twice as an input to the second test. Think about how you could rearrange that to only use the output from the first test once. You should only need two AND gates for the second test. Whip up a diagram in the editor and see what you can come up with. Move the output from the first question to the input of the AND gate on the right. Now you can use just one of the AND gates to the left. Now, look at the third test and see how you could simplify its use of the output from the second test.
