The image illustrates a Master-Slave Flip-Flop circuit. This sequential logic circuit is essential for digital electronics, particularly in data storage and transfer devices. ### Components and Connections: 1. **Master Flip-Flop:** - Label: Master - Inputs/Outputs: - Input `D` (Data): Receives the input signal. - Clock `CLK1`: Triggered by the clock signal. - Outputs `Q` and `Q̅` (Q bar): Deliver outputs based on the input signal. - The lower part is labeled `L1`, which indicates the latch within the master flip-flop. 2. **Slave Flip-Flop:** - Label: Slave - Inputs/Outputs: - Receives data from the master flip-flop via signal `N1`. - Clock `CLK2`: Also controlled by the clock signal, but operates on an inverted clock phase compared to the master. - Outputs `Q` and `Q̅` (Q bar): Emit the stored signal after the clock cycle. - The lower part is labeled `L2`, indicating the latch within the slave flip-flop. 3. **Clock Signal:** - A common clock signal `CLK` triggers both the master and slave flip-flops. - An inverter is placed in the path to the slave flip-flop, ensuring that slave flip-flop operates during the opposite phase of the clock cycle compared to the master. ### Functionality: The Master-Slave Flip-Flop holds data on the falling edge of the clock signal, allowing for synchronization in data processing. Initially, the master latch captures the input signal when the clock is high. During the transition of the clock signal to low, the captured data is transferred to the slave latch. This diagram is crucial for understanding how digital systems manage and stabilize data using flip-flops.
