Abstract: A digital/analogue communication system is described, where data is generated and received by a processing unit in a digital format and transmitted via a communication path in an analogue format. A DSP unit receives a sequence of multi-bit digital samples at a first sampling rate and generates a plurality of interpolated samples. A bit generation unit receives the multi-bit digital samples and the interpolated samples and generates a sequence of single-bit digital samples at a second sampling rate which is higher than the first sampling rate. A set of single wire communication paths are used to convey the single-bit digital samples to respective digital to analogue converters. The use of single-bit digital samples allows them to be held in a buffer. A buffer controller can be provided to delete single-bit digital samples from the buffer so as to match the sampling times at at least one reference frequency of a received signal with sampling times of a generated signal.
