In this paper, two reverse converters for the four-moduli set $\{2^{n},\ 2^{n}-1,\ 2^{n}+1,\ 2^{n-1}-1\}$ are described. One of these is based on Mixed Radix Conversion (MRC). Another converter is based on two-stage MRC in which two pairs of moduli are considered and intermediate results are obtained using MRC. A second stage uses MRC to obtain the final decoded number from these intermediate results. Both the converters are compared with previously reported converter for this moduli set regarding hardware resources and conversion time. Synthesis results on FPGA and ASIC are also presented.
