Every Wednesday, Michio Kaku will be answering reader questions about physics and futuristic science.  If you have a question for Dr. Kaku, just post it in the comments section below and check back on Wednesdays to see if he answers it.

Today, Dr. Kaku addresses a question posed by David Russell: Don’t we lose information when digital signals try to replicate an analog wave pattern?
