Digital base-band signal generator design
Profession:Electronics and information science and technology

Abstract
: FPGA-based design a letter-number generator with, first of all we briefly introduce unipolar NRZ code, bipolar
NRZ, Unipolar zero yards code, bipolar zero yards code, differential code , alternating polarity code, phase code, code-reversal,
and third-order high-density bipolar codes etc. Then we design generator module under the code-conversion design principles.
As EDA technology can make circuit simple, integrate multiple chips, reduce the size of circuits, so we take advantage of
VHDL to describe it and use maxplusII software to simulate .Finally we integrate all the fetures into the FPGA, and design
circuit to generate stable and reliable base-band code to meet the different base-band digital transmission system needs.
Key words
: digital base-band code; EDA; VHDL; PCB; FPGA
