Construction insight: Can a D flip-flop be formed by simply inserting an inverter between the SET input and the clock terminal? Evaluate this claim relative to standard D flip-flop implementations from latches or J–K equivalents.

Introduction / Context:
Understanding how different flip-flops relate helps when converting between primitives or when a required type is unavailable. A D flip-flop can be constructed from lower-level elements, but the relationships must preserve synchronous behavior and proper control of set/reset paths.

Given Data / Assumptions:

• SET and CLEAR are asynchronous override inputs on many flip-flops.
• The clock input governs synchronous sampling of the data path.
• The claim suggests adding an inverter between SET and CLOCK to create a D flip-flop.

Concept / Approach:
A valid construction routes combinational logic so that the synchronous data path implements Q(next) = D at the active clock edge. Typical conversions include: building a D flip-flop from a pair of level-sensitive D latches (master–slave) or from a J–K by wiring J = D and K = D’ (complement). Inserting an inverter between SET and CLOCK does not create a proper synchronous data path; it misuses an asynchronous control and risks forcing states independent of clocking, violating setup/hold timing and the intended function.
