- What Is the jobs done by registers inside a CPUIn 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 exists: (1) there is no paper in the paper feeder tray; or (2) the two micro-switches in the paper path are activated, indicating a jam in the paper path. The presence of paper in the feeder tray is indicated by a HIGH at logic signal P. Each of the micro-switches produces a logic signal (Q and R) that goes HIGH whenever paper is passing over the switch to activate it. Design and build the logic circuit to produce a HIGH at output signal S for the stated conditions, and implement it using the two-input NAND chip.In 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 exists: (1) there is no paper in the paper feeder tray; or (2) the two micro-switches in the paper path are activated, indicating a jam in the paper path. The presence of paper in the feeder tray is indicated by a HIGH at logic signal P. Each of the micro-switches produces a logic signal (Q and R) that goes HIGH whenever paper is passing over the switch to activate it. (3) Regardless the state of the previous two statements the stop signal is active if there is no internet connection to the machine or if the inside temperature sensor is active (This sensor is active if the inside temperature of the machine reaches a certain threshold temperature). Design and build the logic circuit to produce a HIGH at output signal S for the stated conditions.
