Description and Objectives
The purpose of this assignment is to help you practice the following skills that are essential to your success:
Turn a dimensioned 2D engineering drawing into a 3D CAD model
Use a CAD software
Learn the importance of detail and accuracy when communicating
(Engineering drawings and CAD models are still forms of communication!)
Instructions
Utilizing your desired CAD software of choice (e.g., tinkerCAD, rebate a 3D CAD model of
Take multiple screenshots of your CAD model from various angles and paste them into a single pdf file. Choose the angles that show the ‘3D nature’ and various features of your model, e.g., be close to the ‘isometric view’ (google what it is!).
If you look at the front and side views (the two at the bottom), the part above the semicircle of radius 0.5 is supposed to have square cross-section (side 0.36) and height 0.97-0.5 = 0.47. Given this hint, there is something ‘slightly’ incorrect in the provided front and side views. Can you tell what it is?
Submission Format
Each individual student will submit a single pdf file containing multiple screenshots of your final 3D CAD drawing. Ensure that the zoom level of the screenshot is appropriate and sharp enough to see clearly.

Submit 3 files: the .c file, MIPS .asm file and a report in .doc, .docx or .pdf format including a description of your project, progress to date, screenshots of operation, and your current C and MIPS source code MUST be pasted into the end of the report.
Some part of the MIPS assembly code is required for this submission and you should be testing it, but it does not have to be working yet.
Submit the initial, simplified version of your project report with screenshots showing the results and project code written in C here. Your main() function should compile and execute without errors, even if it isn’t completely functional. The initial version will be the skeleton of code to be filled in later.
It must include the basic structure of your final project, written in C with comments and stub code (empty, like prototype functions) that define arguments and return values. I/O and other features that are not complete can be faked by using scanf/printf, initialized variables, strings, arrays, etc.
This code should become the high level definition and pseudocode for your final project MIPS assembly code. By the time you complete the first version of the MIPS code, it should embody the basic logic and algorithms used in this version of your C code.

Can you please finish for me the lab report 2 as the attachment I send to you ? You have my docs for tables in lab

In this project, we will be simulating an EEG (or ECG) amplifier circuit using LTSpice. Other circuit simulation software can be used. (Figure below can be downloaded. Right click and save image.)

Instructions:
Use the above link under ‘Additional Resources’ that refer to generating a spice model for an AD620N chip. The link explains how to create a new circuit symbol in LTspice for the AD620N chip.
For the input signal to the amplifier circuit, there are two sinusoidal inputs. For the amplitude of the sinusoids, a good range of values would be around anywhere from 50uV to 100uV. You can change the amplitude and phase of the two sinusoids. The amplifier amplifies the difference of the two sinusoids. The two sinusoids can have different amplitudes, phase, and frequency. The amplifier will amplify the difference.
Probe the node where the sound card is supposed to be, to view what the output signal looks like.
The frequency of the input signal can range anywhere in the range of EEG brain waves. Alpha waves: 8-13 Hz
Beta waves: 15-40 Hz
Delta waves: 0.1-3.5 Hz
Theta waves: 4-8 Hz
When setting up the transient analysis in LTspice, the stop time can be anywhere from 1us (microsecond) to 5us (microseconds). You can leave the step size and other parameters blank. Just the stop time is sufficient. Depending on the computer, CPU, and RAM, the simulation time can vary. When running the simulation, by pressing the ESC key, you can view the output voltage in real-time as LTspice is running the simulation. (Note: 5u stands for 5 microseconds and 5m stands for 5 milliseconds in LTspice.)
After running the simulation, you can probe the output node and/or the node where the audio connector goes that connects to the speaker.
Take a screenshot of this output graph.
Also, probe the input signals, and plot the difference of the input signals. Or, you can simply plot the two input signals separately.
Report submission:
Copy and paste the screenshots of the following:
Circuit schematic
Output voltage graph
Input voltage graphs (or a graph of the difference of the input voltages)
A short one sentence description under each figure describing what the that figure is about. (E.g. Under the output voltage graph, ‘Graph of output voltage of xx amplifier circuit that amplifies the difference of two input sinusoidal signals with amplitudes of 20mV and 18mV and frequency of 10Hz.’)

I need help with writing the report. The report should be written step-by-step each step you will say how you did it and you will add the table or drwthat is showing on this paper for each step and answer the question that is on the paper each step
