Abstract
Abstract A plurality of preamplifiers divide a wideband frequency range into a plurality of different, contiguous frequency regions. A frequency translator is coupled to the preamplifiers to translate the frequency regions to the frequency region of one of the preamplifiers. An arrangement is coupled to the frequency translator to recover intelligence, or to determine the frequency of the signal, contained in the wideband frequency range.
