ECE 538 Assignment 8

Your submission should follow our general guidelines. Please follow object-oriented principles. Include an executable jar file for each program.

  1. Extend your circuit analysis program to handle multiple voltages sources, such as the example below, and calculate the unknown node values. Display your results in a TextArea and use a JMenuBar as in the previous assignment. Format your node variables to distinguish voltages from currents. In the example, there are four nodes and two voltage sources, so the matrix is 6 x 6 and the node values would be:
    V(1) = ***
    V(2) = ***
    V(3) = ***
    V(4) = ***
    I(1) = ***
    I(2) = ***

    R3 2 0 500
    R4 4 0 200
    VA 1 0 9
    VB 3 2 5

  2. Modify your earilier image display programs so that you can use a growbox to do the equivalent of imcrop in MATLAB. Your program should write out the cropped image to an output image file.

  3. Modify your Java program from previous assignments so that you can also select and draw wires with a mouse, using growline. The netlist description of a wire could be
