THANK YOU ONE AND ALL!!!!! I had looked at the photo and tried to start figuring the math to create the block-I am not good at math so shut down for a while. Thanks to those who searched,or knew where to look, and to those who did the block diagram. I do love the other patterns that were found and will check them out as well. I had tried to send a FB msg to the woman mentioned in the photo-but may never get a reply since it went to her "other" folder.

All of you are wonderful--Happy New Year!!!!!
