Electronics Workbench, Micro$oft Word, and Base Numbers

Introduction (5 points):

      Analog and digital circuits can be very complex. Design and analysis of such circuits can be both tedious and error prone if done by hand. Simulation software has been developed to help overcome such problems. One such simulation program is Multisim. MultiSim is a fully featured electronic circuit simulation tool. However, many of its capabilities are not needed for this lab. Therefore, we use a program that implements a subset of MultiSim's capabilities. That program is Electronics Workbench. Electronics Workbench is the simulation program that will be used in this lab.
      Since digital electronics uses two logic states to implement discrete mathematics and Boolean Algebra, binary numbers are used for modeling and analyzing this system of electronics. However, binary numbers can be highly inefficient and cumbersome when humans use them to perform certain numerical calculations. Therefore, digital engineers should know how to convert between different base number systems (especially binary, octal, and hexadecimal).

Objective (5 points):

      The purpose of this lab is to introduce students to Electronics Workbench (EWB) and Micro$oft Word, and to also give them HANDS-ON experience  converting numbers from one radix to another (hexadecimal, octal, binary, and decimal).

Procedure (80 points):

  1. Introducing Electronics Workbench  (42 points):

    Following the instructions of the TA,  design a circuit that converts binary to hexadecimal using 7-segment LED displays, switches, power, and ground.  You can refer to a very simple EWB Tutorial (written by Scott Fritzinger, modified by Kim Martin and Beifang Yi).  With EWB design a circuit that shows a hexadecimal number "B6" and copy the circuit to your lab report. (Note: the MSB--Most Significant Bit should be the leftmost bit in any number).An example circuit
