Claim:
1. A method for processing a received signal, the method comprising: digitizing each of a plurality of component signals, each component signal comprising a respective frequency band of the received signal; frequency-shifting the component signals such that the respective frequency band of each component signal has a respective region of overlap with the frequency band of at least one other of the component signals; filtering the component signals, by a digital filter, after said digitizing and before said frequency-shifting, such that the sum of the component signals has a unity frequency response within the regions of overlap; adjusting the gain and phase of the component signals such that the sum of the component signals has a continuous frequency response over an aggregate frequency band comprising each of the frequency-shifted frequency bands; and summing the component signals to obtain a composite signal; wherein said digitizing, frequency-shifting, filtering, and adjusting the gain and phase are performed for each component signal by a respective phase-locked, time-synchronized vector signal analyzer.
