ECE 152A LABORATORY 1 _________ Preliminaries : The Seven-Segment Indicator The seven-segment indicator is a display with 7 segments each of which can be lit independently of the other six segments. This is shown in Figure 1. This indicator can be used to display the digits 0 through 9 (just like on old calculators), or it can be used to display some letters (such as on pagers that have alphanumeric characters). In this lab, we will use the seven-segment indicator to display letters. Objective : Design a circuit that displays the letters A through J on a seven-segment indicator. The circuit has four inputs W, X, Y, Z, which represent the last 4 bits of the ASCII code for the letter to be displayed. For example, if WXYZ = 0001, "A" will be displayed. The letters should be displayed in the following form: Deliverables and Due Dates: Lab # 1 Problem Set is due beginning of your lab section. This comprises completing the Steps 1, 2 and 3 below. (See the "Design Steps in Detail".) In addition, you HAVE to come to the lab having read the data sheets for this lab. Please go to the course web page to read and print the TTL data sheets that you may need to refer to for this lab. Figure-1 Figure 2
