BASIC ENGINEERING PROBLEM!?

You are working on setting up a security system for your apartment that has two large windows and one front entrance door. You install two sensors A and B on one of the large windows and want the alarm to sound if both sensors indicate intrusion. Similarly, sensors C and D are installed on the other window and the alarm should sound if both sensors indicate intrusion. Sensor E is installed on the front door and the alarm should sound if there is an intrusion.


Each of these sensors represents a binary logical variable with a value of zero when there is no intrusion and a value of one when there is an intrusion. The logic variable F represents an alarm for which a zero represents 鈥榥o alarm鈥?and a value of one means 鈥榓larm sounds.鈥?Express the logical variable F as a function of logical variables A, B, C, D and E and write the Truth Table for it.





pleaseeeeeee help! and thank you in advance(:|||In programmerese If (A AND B)=1 OR If (C AND D)=1 OR If E=1 then F=1
