Definition of Synchronous
The term synchronous refers to a type of digital circuit or system where the output changes state only when the clock input is triggered. In other words, the output of a synchronous circuit is updated or synchronized with the clock signal.
Explanation of the Answer (Option B)
Synchronous Circuit Operation
- A synchronous circuit operates using a clock signal, which is a periodic waveform that oscillates between two voltage levels (typically 0 and 1).
- The clock signal is used to synchronize the operation of the circuit, ensuring that all changes in the circuit occur at specific points in time.
- The clock signal is applied to the clock input of the circuit, and the circuit responds to the changes in the clock signal.
Triggering of Output State Change
- In a synchronous circuit, the output changes state only when the clock input is triggered.
- This means that the output remains stable or unchanged until the clock signal transitions occur.
- When the clock signal transitions from one state to another (e.g., from low to high or high to low), the output of the circuit is updated based on the input values at that point in time.
- The circuit evaluates the inputs and determines the new output based on predefined logic or rules.
Advantages of Synchronous Circuits
- Synchronous circuits offer several advantages over asynchronous circuits.
- The use of a clock signal allows for precise timing control, ensuring that all changes occur at specific points in time.
- Synchronous circuits are easier to design and analyze because the timing and behavior of the circuit are well-defined.
- Synchronization with the clock signal helps to minimize the occurrence of hazards or race conditions that can occur in asynchronous circuits.
- The use of synchronous circuits simplifies the design of complex digital systems by allowing for modular design and easy integration of multiple components.
Conclusion
In summary, the term synchronous in the context of digital circuits refers to a system where the output changes state only when the clock input is triggered. The use of a clock signal allows for precise timing control, making synchronous circuits easier to design and analyze compared to asynchronous circuits.
