A multi-channel filter which exploits the parallel processing advantages of an optical signal processor is used to sort, classify and remove noise or unwanted signals from signals of interest. This filter shall perform real time parallel signal processing to effectively channelize and remove unwanted spectra from the various signals of interest in a dense radio frequency environment. This would in effect transform a single channel that is corrupted with unwanted signals, interference and noise, to a number of discrete channels which is spectrally tailored to selected signals of interest. The filtering process is accomplished by modulating a laser carrier with the given signal of interest and performing all filtering functions optically and then down converting the filtered signals back into its original radio frequency for further use.
