What is a communications system in which spread-spectrum techniques are used to multiplex more than one signal within a single channel?

A) CDDA B) CMMA C) CDMA D) CSMD

Input an integer containing 0s and 1s (i.e., a “binary” integer) and print its decimal equivalent. Appendix C, Number Systems, discusses the binary number system. (Hint: Use the mod- ulus and division operators to pick off the “binary” number’s digits one at a time from right to left. Just as in the decimal number system, where the rightmost digit has the positional value 1 and the

next digit leftward has the positional value 10, then 100, then 1000, etc., in the binary number system, the rightmost digit has a positional value 1, the next digit leftward has the positional value 2, then 4, then 8, etc. Thus, the decimal number 234 can be interpreted as 2 * 100 + 3 * 10 + 4 * 1. The decimal equivalent of binary 1101 is 1 * 8 + 1 * 4 + 0 * 2 + 1 * 1.) What will be an ideal response?
