Abstract

A system and methods to convert a digital bit stream to analog values without previous knowledge of the sample rate of the incoming digital bit stream has been achieved. The system comprises a sample rate measurement device being able to measure the sample rate out of the incoming digital bit stream. Another device is removing all bits, which are not required for the digital to analog conversion from the incoming bit stream. The measured and calculated sample rate is added to the “cleaned” bit stream and a digital to analog conversion device is performing the conversion using the sample rate which has been added to the bit stream.
