Copy and paste the M-file into a text document. For problems 1 and 2, include in the text document the pictures produced by MATLAB. Resize and crop the pictures so that they do not take up too much space. If the question requires written answers, include them in the text file in the appropriate location. Make sure you clearly label and separate all the Exercises. For problems 3 and 4 you do not need to include the picture. 1. Determine the shearing transformation matrix that shears 1 units in the vertical direction. Plot the original square together with the sheared square. Use axis((-1,3,-1,3]);. Add a grid, a legend and a title (similarly to EXAMPLE 4). Include the M-file as well as the figure. 2. Consider the original square S. First apply the shear transformation from EXAMPLE 4 and then rotate the square 45° counterclockwise. Plot the resulting figure (together with the original square) and compare with the plot in Example 5. Are the results the same? Does the order of the transformations matter? Include the M-file as well as the figure and don't forget to answer all questions. Hint: Here you want to apply the shear first, then rotate, whereas in Example 5 the square is first rotated and then the shear is applied. To do this, TQS = T*Q*S, where Q is the rotation matrix and T is the shearing transformation matrix. So, if you want to first shear and then rotate, in what order will you multiply the matrices? EXAMPLE 4 We will apply a horizontal shear transformation of 3 units. The matrix that accomplishes that is T = We can plot the original square together with the sheared version by executing the 0 following commands.

  Problem Statement Design, simulate, and build a 3-bit Digital-to-Analog Converter with full-scale analog voltage, V FS = 5V. Note that some terms used in this document refer to concepts and/or quantities that we do not explicitly study in 2EI4. Part of the project is for you to conduct research to learn the meaning of these concepts and/or quantities to be able to complete the design and write the report. Examples of these are the full-scale analog voltage (VFS), the gain error, the maximum differential non-linearity, etc. Design Contraints 1. You are limited to the dc supplies available from your Digilent module. 2. You are limited to op-amps, transistors, and resistors from your 2EI4 and 2CI4 kits. 3. Current drawn from the digital bit lines cannot exceed 1μA (ideally 0). 4. The bit levels are 0V (logic low) and 5V (logic high). 5. For convenience, you are allowed to treat 0V on a bit line as logic-1 and 5V as logic-0 (i.e. if your design requires the inversion of the bit lines, you don’t actually have to build the three inverters). Please provide the design circuit with proper description.
