Abstract
Receiver embodiments are disclosed that can process a wide range of transmission bandwidths over a wide range of transmission frequencies and provide reduced converter sampling rates, filter bandwidths, and filter tuning ranges and enhanced signal-to-noise performance. They convert transmission signals with quadrature local oscillator signals whose frequencies are commanded to be a selected transmission frequency when a selected transmission bandwidth is above a predetermined bandwidth threshold and are commanded to be offset from the selected transmission frequency by an intermediate frequency that is at least one half of the selected transmission bandwidth when the selected transmission bandwidth is below the bandwidth threshold.
