1.Clock Signals:-As we know that the microprocessor operates with reference to clock signals provided to it. At pins X1 and X2 we provide clock signals and this frequency is divided by two. This frewuency is called as the operating frequency.
2.Single Line Signal:-The status of single line will be either LOW or HIGH. But the change from one state to another state is not possible in zero time.
3.Multiple Line Signals:-In Microprocessor we have multiple lines. These signals are also called as bus signals. If a single line changes occure then we have to show a crossing to indicate change in contents.
