Abstract

An analogue to digital converter (ADC) (5) comprises a comparator (14); an N x 1-bit clocked shift register; and a clock. Such an ADC is suitable for use in a system for controlling the envelope of a periodic waveform. The system comprises an ADC according to the invention and processing means, whereby the ADC samples an input waveform and the processing means determines a correction waveform, converts the correction waveform to an analogue signal, combines the correction waveform with the input waveform to control its envelope and outputs a combined waveform, wherein the combined waveform is substantially flat.
