An analogue-to-digital conversion arrangement employs a CW laser, which is ramped in wavelength over a given wavelength range for a given time, to drive a modulator whose modulating input is an analogue signal to be converted. The modulator feeds wavelength-splitter having a number of channels centered on different wavelengths within the wavelength range, the outputs of these channels being converted into respective analogue electrical signals, conventional ADCs being finally used to convert these signals in turn into digital signals.
