01 Using a number of (IK x 4) ROM with enables E and with address Ag A .. . An in addition to a decoder and OR gates, construct a 4K x 4 ROM with addresses Ao Ai... Anm a) Determine n and m b) Sketch the required design in block diagrams and show clearly the address connections. 02 Design a ROM with three address lines Az Ai Ao and four outputs B; B2 Bi Bo, each output may be represented as a function of the inputs A2 Ai Ao as follows: Bo= 1 Bi = Ai Obtain the full truth table and construct the ROM using a decoder and OR gates. Show clearly the blown and the intact fuses
