Final answer:
The student's question involves creating input-output logic tables and schematic drawings for various digital logic components, including NAND and NOR latches, and synchronized S-R, J-K, and D flip-flops, which are used to store and manipulate digital information.the correct option 1s:a. NAND Latch
Step-by-step explanation:
To answer your question about digital logic circuits, we need to create input-output logic tables for different types of latches and flip-flops, and also provide schematic drawings for each.
- NAND Latch: A NAND Latch is a basic memory device that holds one bit of data. It has two inputs, traditionally labeled S (Set) and R (Reset), and two outputs, Q and Q'. When S is high and R is low (1 and 0), the latch sets; when S is low and R is high (0 and 1), the latch resets. If S and R are both low, the output remains unchanged.
- NOR Latch: Similar to the NAND latch but with NOR gates. The logic is reversed; the latch sets when both inputs are low and resets when one input is high.
- Synchronized S-R Flip-Flop: This flip-flop adds clock synchronization to the S-R latch, so the S and R inputs are only considered when the clock input (CLK) is high.
- Synchronized J-K Flip-Flop: The J-K flip-flop functions like an S-R flip-flop but with two additional inputs, J and K, which can toggle the output state when both are high and the clock transitions.
- Synchronized D-Flip-Flop: This flip-flop has a single data input D and transfers the D input to the Q output on the rising edge of the clock signal.
Each flip-flop type has its own characteristic table, which lists the possible states of inputs and the resulting outputs. Additionally, schematic drawings would show how the gates are interconnected to form each type of flip-flop or latch.the correct option 1s:a. NAND Latch
