Computer Problems 2.80 Consider the process flow diagram shown in Fig. 2.14. We can write this out as the system of equations 2 3 4 5 m = m2 + m3 + m4 +m5 m2 = mg + m10 + m11 m5 mg + m7 +m6 Figure 2.14 Process schematic for Problem 2.80. 9 10 8 7 6 11 12 1. Find datasheets of 7447 and 7448 ICs. What is the main difference in application between common anode (7447) and common cathode (7448) ICs? What is the nominal supply voltage (Vcc)? 2. Draw the circuit schematic of connecting a 7447 IC to a 7-segment LED display in Proteus Software (available in MSE 4290 lab computers). 3. What is the application of the Ripple Blanking Input and Ripple Blanking Output pins on the 7447 and 7448 ICs? Demonstrate their application by creating a 3 digit BCD to 7 segment display converter in Proteus.
