Can someone please help me with buildning this ""inovation" into a diagram; The output is that 1. a alarm speaker turns on, 2. Lights are turning on in the house & 3. Cameras are beginning to take pictures of the surrounding. All these three outputs are going to be linked to an OR-gate. This OR-gate will then be linked to two more OR-gates. One of these two OR-gates will be linked to magnetic contacts & to the control panel of the larm. The other OR-gate will be linked to a motion detector & to glass break detector. (You do not have to search and find the right symbols for all of these elektronic components. I only want your help to sketch/ draw how the diagram will look. I know how the the sketch is that i will poste with this question but I want to know how the diagram will be) Please help me! |

These all seem to be remote signals so I would suggest that you filter them and apply a threshold before applying them to your logic circuit. A good way to do this is to use comparators to compare each input with a known voltage. The comparator outputs can be wire-or'd together with a single pull-up resistor. The alarm at this point will be active low. Add further comparators to drive your alarm bells and whistles. Please ask your prof to award the marks for this answer to my account as usual. |
