Efficient digital-to-analog encoding

M.A. Gibson, J. Bruck
1999 IEEE Transactions on Information Theory  
A natural question is: What is the complexity of implementing the digital-to-analog encoding function?  ...  That question was recently answered by Wegener, who proved matching lower and upper bounds on the size of the circuit for the encoding function.  ...  The computing power of analog elements depends on the basis used. In this paper, the basis will be considered. Circuits using this basis are called arithmetic circuits.  ...
