Stanford Engineering Puzzle

January 2009

Electrical engineers know their way around the process of analog to digital conversion (the process of taking a continuous signal such as sound and making it a discrete one), but anyone can tackle the task the way we present it below. Your job this month is to convert one term to the other, one letter at a time. Along the way you'll beforming new words each turn.

Marge Kastner created this puzzle.

Directions

Starting with the word "ANALOGS" change one letter to form a new word suggested by the clue on the next line. The first one is done for you. Keep going that way until you need to change one more letter to spell digital. When you are done, send the secret "word" to Marge, which is to say the first letter of the first row, the second letter of the second row, all the way up to the seventh letter fo the seventh line. Have fun.
