Q1 (a) The key to the main entrance door of the Faculty of Engineering Sciences building of University of Ghana is to be replaced by an electronic key system. An electronic key that has four input knobs, A, B, C, D is to be used to generate the required output signal Y needed to open the door. Design a logic circuit for the electronic key, if the following conditions are required. Y=1 when A and B are both 1, subjected to the conditions that C and D'are both Low or both High [10 marks] (b) List the systematic procedure used to achieve the designed logic circuit for the electronic key in Q1 (a) (c) Identify the circuit in figure 1 and write the Boolean expression for the circuit, if ABCD are the address lines and a and b are the address select (control) lines [3marks] [7 marks] Inverters a *AND" gate A *OR" gate B D Figure 1 mO00 Q1 (a) The key to the main entrance door of the Faculty of Engineering Sciences building of University of Ghana is to be replaced by an electronic key system.
