This lecture was presented by Professor Malcolm Hawksford in the spring of 1996 and formed part of a 1-week specialist short course as a module of the MSc in on Audio Engineering at Essex University, UK. Students participated both in the UK and simultaneously in Finland via an ISDN video link. The lecture reviews the fundamental principles of digital audio including sampling theory, quantization, dither, jitter, sampling-rate conversion and noise shaping. The lecture also discuses ADC and DAC techniques and shows how noise shaping can facilitate an exchange between sampling rate and word depth that spans both multi-bit formats including the special case of the 1-bit code (SDM) that forms the backbone of DSD. A DAC architecture using a raised-cosine interpolation technique is also described which can lower susceptibility to jitter and transient induced distortion that can occur in the I_V stage of a DAC.
