I will refrain from any form of academic dishonesty or deception, such as cheating or plagiarism. I am aware that as a member of the academic community it is my responsibility to turn in all suspected violators of the honor code. I understand that any failure on my part to support the Honor System will be turned over to a Judicial Review Board for determination. I will report to a Judicial Review Board hearing if summoned.

Abstract: In this lab we will be observing and analyzing Multisim circuit configurations consisting of a variety of registers and their counterparts. Documentation of the functionality of each circuit will be conducted by implementing the measuring tool consisting of a virtual Logic Analyzer assisted by the Word Generator configuration in each circuit. This lab will provide the ability to observe the functionality of specified shift registers and to diagnose faults by obtaining the timing diagrams, analyzing the clock pulses, and observing the results. Introduction: In EET230 the functionality of shift registers was introduced. The circuit configurations consisting of a 5-bit Register, 4-bit Parallel In/Serial Out Register, 4-bit Bidirectional Shift Register, and a10-bit Ring Counter will be observed and analyzed in Section I. The circuit configuration in Section II consisting of a 10-bit Ring Counter requires the recognition and diagnoses of a faulty functioning circuit. In addition, the proper configuration of the components can be analyzed and observed by means of the logic analyzer to check the outputs and to provide a digital waveform according to the function generator’s clock signal settings. This lab will demonstrate how the various types of shift register configurations function correctly and produce the specified clocked digital signals accordingly. As well as providing an understanding of how to diagnose a faulty 10-bit Ring Counter. Below are the fundamental concepts for successfully completing the lab: Asynchronous : Refers to events that do not have a fixed time relationship with each other and, generally, do not occur at the same time. An asynchronous counter is one where the flip-flops within the counter do not change states at the same time because they do not have a common clock pulse (Floyd, T.). Synchronous: Refers to events that have a fixed time relationship with each other. A synchronous counter is one in which all the flip-flops in the counter are
clocked at the same time by a common clock pulse (Floyd, T.). The clock pulses are applied to all the flip flops in a counter simultaneously.
