ET1220: Module 3 Logic CircuitsExercise 3.1Combinational Logic, Networking, and Interfacing1Answer the following questions:1.Assume that the tablet bottling control system is set for 36 tablets per bottle. Determine the binarynumbers in register A and register B after 5 bottles have been filled. If one more bottle is filled, whatwill be the output of the adder?2.What full-adder inputs will produce the following outputs?3.The input waveforms in the figure below are applied to a 2-bit adder. Determine the waveforms forthe sum and the output carry in relation to the inputs by constructing a timing diagram.4.In the process of checking a 4-bit parallel adder, the following logic levels are observed on theinputs: HIGH (MSB), HIGH, HIGH, HIGH, and HIGH (MSB), LOW, LOW, HIGH. The following levels areobserved on the outputs: LOW (MSB), HIGH, LOW, and HIGH. Determine if the adder is functioningproperly.5.Show the additional logic circuitry necessary to convert the 4-bit look-ahead carry adder in thefigure below into a 5-bit adder.
