Abstract
A signal processor apparatus includes: first and second photonic comb generators generating respective first and second combs with respective different first and second tone spacing; modulator modulating the first comb with an analog input signal; combiner combining the modulated first comb with the second comb and directing the combination results to first and second arms; spectral filter unit for each arm dividing each arm into a plurality of sub-bands; plurality of photodetectors, one for each sub-band of each arm, each photodetector outputting an electrical signal carrying information on the respective sub-band of the input signal; phase-shifter adjusting a relative phase of the first and second combs with respect to each other prior to the combiner; sensor system producing an output related to a phase difference between the first and second combs at the combiner; and controller controlling the phase-shifter based on the output of the sensor system.
