METHOD FOR MODULATING AND DEMODULATING A SIGNAL, SIGNAL MODULATION AND DEMODULATIN APPARATUS FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE APPARATUS

摘要

PURPOSE: A signal, signal modulation and demodulation apparatus for performing the method and display apparatus having the apparatus are provided to improve image quality by transmitting a transmission signal from a modulation unit to a demodulation unit. CONSTITUTION: A signal modulation device includes a signal modulator(510) and a signal demodulator(530). The signal modulator modulates data information and clock information into a carrier signal. The data information is included in the input data signal. The clock information is included in the input clock signal. The signal demodulator demodulates the carrier signal into the output clock signal and output data signal.
