BINARY LOGIC AND GATES Introduction Our objective is to learn how to design digital circuits. These circuits use binary systems. Signals in such binary systems may represent only one of 2 possible values 0 or 1 Physically, these signals are electrical voltage signals These signals may assume either a high or a Low voltage value. The high voltage value typically equals the voltage of the power supply (e.g. 5 volts or 3.3 volts), and the Low voltage value is typically 0 volts (or Ground). When a signal is at the High voltage value, we say that the signal has a Logic 1 value. When a signal is at the Low voltage value, we say that the signal has a Logic 0 value. Hence, the physical value of a signal is the actual voltage value it carries, while its Logic value is either 1 (High) or 0 (Low). ‰Digital circuits process (or manipulate) input binary signals and produce the required output binary signals.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
