Figure 1 shows a simple copy machine, a stop signal, S, is to be generated to stop the machine operation and energize an indicator light whenever either of the following conditions exist: (1) there is no paper in the paper feeder tray or (2) the two microswitches in the paper path are activated, indicating a jam in the paper path. The presence of paper in the feeder tray is indicating by a HIGH at logic signal P. Each of the microswitches produces a logic signal (Q and R) that goes HIGH whenever paper is passing over the switch to activate it. (i) Determine the truth table for the copy machine for the input are P, Q and R and the output is S. (iii) From (a)(i), minimize SOP expression using Karnaugh map simplification.
