Document Summary
Two problems to start off with: assume a temperature is stored in a register as a binary number, assume an alarm is on when it receives and input signal. Set the alarm when the temperature is at or above 5 degrees. There is an alarm, with a wire coming out of it. If it is a 1, the alarm rings. If it is a 0, the alarm doesn"t ring. This devices plugs into our computer and records the temperature. It has a binary value that it stores the temperature register. The goal is to build some circuitry that, when it is 5 degrees, it turns on the alarm. For argument"s sake, let"s say that the register is 4 bits. Since it has 4 bits (for example, 0101), there are four wires coming out of it. So, we want to figure out if it is the number 5 coming out of those 5 bits.
