Abstract
A photonic, wide-band analog to digital converter and method for converting an analog electrical signal to a digital electrical signal by electrical signal processing wherein the analog electrical signal is first converted to an optical signal having a wavelength which is a function of the amplitude of said analog electrical signal. The optical signal is then filtered in a plurality of optical filter channels to create N optical bit signals forming an N bit binary word indicating the wavelength of said optical signal. These optical bit signals are then each converted to an electrical bit signal to form an electrical binary word.
