Latches
  1. How many bits can a latch store?
  1. Complete the truth table for NOR below. 
          A    B   |  (A+B)'
          ---------+--------
          0    0   |
          0    1   |

          1    1   |
  1. Below is a SR latch. There are values on the wires right now. Cross off the 0 on the S wire, change it to 1, and propagate values.
  1. What is it called when the output of a circuit is recirculated to become part of the input?
  1. What do the initials S and R stand for?
  1. Why should we never let S and R both become 1?
  1. If the S-R latch is put into an indeterminate state, does it stay that way forever?
  1. What do we call a circuit that effectively flips a coin and randomly choses 1 or 0?
