EE 210 Lab Report Rubric Adapted from 316 Rubric and Formal Template; Revised by Lin Yi, Spring 2018. 1. This rubric covers the majority of the points required by the Formal Template. Any points taken off will be from this rubric. Although if something is missed, points can still be taken off even if not on the rubric. Be assured that if points are taken off for something not on the rubric, it will be applied to all lab reports. 2. Reports will be graded unnamed, meaning I will not know the name attached to each report until the grade has been recorded and finalized. 3. I will return labs before the next lab is due so that feedback can be received. 4. If there any uncertainties regarding one’s report I can be contacted at yilin@uab.edu. I will also be in room BEC 266. It will be thoughtful of you to inform me your arrival, by e-mail ahead of time. Missing items from your report, and on the right-columns, the points taken off.

Jannett Experiment performed on 24 May 2006 Report submitted on 27 May 2006 EE 210 - Digital Logic Department of Electrical and Computer Engineering The University of Alabama at Birmingham Abstract Simple combinational logic circuits were designed to implement minimal realizations of Boolean functions specified in a truth table. AND-OR and ALL-NAND realizations were employed. The circuits were tested using computer simulation and found to implement the truth table. The abstract should briefly describe what work was done, why it was done, and how it was done (what, why, how). The abstract should present the main results and describe the usefulness of the results. The abstract does not serve as the introduction of the report. The report should stand alone from the abstract, and the abstract should stand alone from the report. The abstract should not cite references and it should not include any figures or equations. Although the abstract appears first in the report, it is written last. The first three sentences of this paragraph are adequate for the abstract of this report.

Karnaugh mapping was used to develop minimal AND-OR realizations. DeMorgan's theorem was applied to produce an ALLNAND realization. A hazard free realization was not required. Computer simulation was used to verify the design. The introduction should state what work or activity was done, why it was done, and how it was done (what, why, how). Theory A theory section is hardly ever used outside of a laboratory report. For a lab report, the theory section should give the background for the methods employed in the work described in the current report. For this report, the theory should the logic for a two-way light switch, minimization of a logic function using a Karnaugh mapping technique, and the development of the ALLNAND realization using DeMorgan’s laws. The report should address your classmates as an audience. As you progress in the course and learn new topics, the topics that made up the theory in an early report will be assumed to be known by all when reports are written for more advanced topics later in the semester; the theory section of the second and later lab reports will not need to describe the Karnaugh mapping technique and the development of the ALL-NAND realization using DeMorgan’s laws. With a two-way light switch, a light is on when either one, but not both, of two switches is on. When both switches are on or both are off, the light is off. A two-way light switch configuration is useful in many applications, including a hallway for which it is desired to be able to control the light using switches placed at both ends of the hall. A truth table for a two-way light switch is shown in Figure 1. X and Y represent the switch states and Z represents the light state, with 1=on and 0=off. Fig. 1.

AND-OR realization for logic function. ALL-NAND realization for logic function. Methods The methods section should describe the methodology used to carry out the work and produce the results. It should list the procedures or techniques that were employed. The methods 2 section is presented in enough detail to allow the experiment to be repeated so that the results are reproduced [2]. The Karnaugh mapping technique was used to produce a minimal AND-OR realization of a Boolean function describing the behavior of a two-way light switch specified by a truth table (Fig. 1). DeMorgan’s laws were used to produce a minimal ALL-NAND realization. The Quartus II software package was used to test circuits implementing AND-OR (Fig. 3) and ALLNAND (Fig. 4) realizations using computer simulation. All possible combinations of 0 and 1 inputs were applied to each circuit. The input patterns and corresponding outputs were used to produce an experimental truth table that listed the circuit outputs achieved for all possible inputs. The experimental truth table was checked against the truth table for the two-way light switch logic (Fig. 1). The parts list describes the parts used. Experimental Procedure Procedure checklist: 1. A schematic file was created and edited to represent the AND-OR version of the circuit (Fig. 3). 2. A waveform editor file was created and edited to represent all combinations of the test inputs. A simulation was run for the AND-OR circuit using the test inputs. 3. The simulated output waveforms were observed. After correcting errors in the schematic and the test inputs, the simulation was run again. After the simulation was debugged, the simulated AND-OR circuit outputs were recorded in an experimental truth table. 4. A schematic file was created and edited to represent the ALL-NAND version of the circuit (Fig. 4). 5. A waveform editor file was created and edited to represent all combinations of the test inputs. The simulation was run for the ALL-NAND circuit using the test inputs. 6. The output waveforms were observed. After correcting errors in the schematic and the test inputs, the simulation was run again. After the simulation was debugged, the simulated ALLNAND circuit outputs were recorded in an experimental truth table.

Computer simulation was used to verify that the circuits behaved according to the truth table. Discuss the results, but do not present the results again. Discuss the agreement between experimental data and expectations. Discuss conflicting data, and procedural issues that may have affected the results.

Abstract
A logic probe is an electrical implement that when connected to a high potential, a Bulb
lights to indicate a high potential and when connected to a low potential the bulb does not
light to indicate that fact. In this experiment, the behaviour of an LED light bulb is
determined and the knowledge of this in conjunction to a not gate is used to come up with a
logic Probe.

Introduction
The purpose of this experiment was to gain experience in the building of circuits to be used in
the testing of different logic states. A Not gate was used in the experiment and a truth table
constructed to show when the LED light would come on. An explanation for this
phenomenon was determined and computer simulations were used to ascertain the results of
the experiment.
Theory
A logic probe is an electrical implement that is used to determine the logic state of a given
point in a circuit. To implement this implement a circuit implementation was used to come up
with the appropriate circuit. The probe is made up of different parts:
a) The LED
The light emitting diode is used in the circuit of the probe to show that the circuit is
connected to either a high or a low. An LED lights when current flows through it in the
positive direction and fails to ligh...

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
