ABSTRACT:
A method and system of representing a signal is disclosed herein. A digital representation of an analog signal is received by a bandwidth detection circuit 14. The digital signal typically, but not necessarily, comes from a analog-to-digital converter 12. The a bandwidth of the signal is determined. The bandwidth is compared to a selected threshold bandwidth. A selected portion of the digital representation is stored in a memory unit 16. The selected portion is determined by a result of the comparison step. A code word is also generated by the bandwidth detection circuit 14 and stored in the memory circuit 16. The original analog signal can be recreated with a decode circuit 20.
