[laurencescou]

The difference between a D-latch and an edge-triggered D-type flip-flop is that the latch:
 
  A) is controlled by the logic level at its ENABLE input rather than a CLK transition.
  B) triggers on either the rising or falling edge of an ENABLE signal rather than the CLK input logic level.
  C) always latches the Q output to the complement of the D input regardless of other inputs.
  D) always latches the Q output to the D input regardless of other inputs.

Question 2

The symbol for a flip flop has a small triangle - and no bubble - on its clock (CLK) input. The triangle indicates:
 
  A) the FF is edge-triggered and can only change states when the clock goes 0 to 1.
  B) the FF is level active and can only change states when the CLOCK = 1.
  C) the FF is an active LOW device and can only change states when the CLOCK = 0.
  D) the FF is edge-triggered and can only change states when the clock goes from 1 to 0.
