Edge Triggers
Edge triggers are essential components in sequential logic circuits, serving as a mechanism for triggering subsequent logic operations when specific input conditions are met. These conditions are defined by the connections made to the edge inputs of logic gates.
An edge trigger essentially acts as a "switch" that opens or closes the gate's output pathway when the input condition is met. The switch is typically implemented using an external controller or a dedicated component within the circuit.
Example:
Consider a sequential circuit with an AND gate (AND) and two input signals, A and B. The output of the AND gate is connected to the gate input of another AND gate.
When either input signal (A or B) is high, the output of the AND gate will be low. This is because the two inputs are logically connected through the AND gate, and when one input is high, the other must be low for the output to be low.
Edge triggers can be used to create complex sequential logic circuits by connecting multiple inputs and outputs together. By defining appropriate input conditions through the edge trigger connections, we can trigger specific operations when specific inputs are activated
