Abstract
A signal monitoring system includes a splitter circuit, a single-bit channel circuit, a multi-bit channel circuit, and a frequency processor circuit. The splitter circuit splits a first analog signal into second and third analog signals. The single-bit channel circuit samples the second analog signal at a sampling rate that is greater than or equal to a Nyquist rate of the second analog signal to generate a first digital signal. The multi-bit channel circuit under-samples the third analog signal at a sampling rate that is less than a Nyquist rate of the third analog signal to generate second digital signals. The frequency processor circuit resolves a Nyquist zone ambiguity in the second digital signals using the first digital signal to generate an unambiguous output signal.
