Verify D-to-T Conversion: Trace Q Through XOR Gate
A T flip-flop can be configured to act as a D flip-flop by driving its toggle input with the XOR of the desired data input and its current state. Four signals are shown: CLK (clock, period 2), D (external input), T (internal combinational node), and Q (flip-flop output). The positive-edge-triggered T flip-flop updates Q on every LOW-to-HIGH transition of CLK based on the value of T immediately before the edge. The internal node T continuously evaluates to D XOR Q. Trace both T and Q across all 12 time steps, starting with Q initially at 0.
Constraints
Qonly updates its state on the rising edge ofCLK.Tis a combinational node and updates immediately wheneverDorQchanges.
