1. A sequential circuit has two D flip- flops, one input X, and one output Y. The logic diagram of the circuit is shown in the following Figure. Derive the input equations, output equation, the state table and state diagram of the circuit. 2. Time Diagram: Clock and D waveforms, a D latch and an edge- triggered D Flip-Flop are shown in the following Figure. For both the latch and the Flip-Flop, carefully sketch the output waveform, Qi, obtained in response to the input waveforms. Assume that the propagation delay of the storage elements is negligible. Initially, all storage elements store 0 01 02
