5. a 2-bit encoder is a circuit with four input lines, exactly one of which is high at every instant, and two output lines whose 2-bit binary value tells which input is high. only one of the input lines will ever be active at the same time. you do not have to consider the cases if more than one is active. a. draw the truth table for a 2-bit encoder. there will be four input variables and two output variables. only one of the input variables can be 1 at a given time, so there are only 4 possible combinations for valid input variables. b. draw the circuit for the 2-bit encoder. c. draw the circuit for a 3-bit encoder. there will be 8 input lines and 3 output lines.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
