1. The $7474\mathrm{D}$ flip-flop IC is and edge-triggered device. Explain what is meant by edge-triggered and how this affects the transitions in output $Q$. 2. Which are the synchronous and which are the asynchronous inputs to the $7474\mathrm{D}$ flip-flop IC? 3. A series of $\mathrm{D}$ flip-flops in which the output from one is the input to the next, as shown in the figure below, represents a 4-bit shift multiplexer. TRUE or FALSE? 4. Review the VHDL Primer from Brightspace. According to the VHDL Primer, VHDL keyword and identifiers are case sensitive. TRUE or FALSE? 5. Review the VHDL Primer from Brightspace. Provide the VHDL statement that would output the Boolean expression to $\mathrm{X}$, as it would appear in the Architecture section of a VHDL program.
