Abstract
A system for converting a continuous-time analog signal having a signal bandwidth to a discrete-time digital signal, the system includes a plurality of proportional filters configured to receive the continuous-time analog signal, each proportional filter having a different center frequency from all other proportional filters and each proportional filter having an operational bandwidth directly proportional to its center frequency, and a plurality of sample and hold circuits, each sample and hold circuit coupled to a respective one of the proportional filters.
