This paper introduces the design and implementation of an EFM/EFM+ demodulator
which is used in the DVD servo control system.The demodulator translates the 14-bit CD data and the 16-bit DVD data into 8-bit data.The final solution has been given by analyzing the principle and the practical application.The demodulator has been implemented in Verilog Hardware Description language.And the simulation result and the FPGA verification indicate that the design is successful.
