Claim 0:
1. A modulation method for modulating n-bit data, the modulation method comprising:
forming a time difference between a sync impulse and a data impulse to correspond to p-bit data;
modulating the amplitude of the sync impulse to correspond to q-bit data and modulating the amplitude of the data impulse to correspond to r-bit data; and
combining the sync impulse and the data impulse,
wherein the forming of a time difference comprises:
receiving a clock signal and delaying the clock signal to correspond to the p-bit data to form a data edge;
forming a sync window corresponding to an edge of the clock signal and a data window corresponding to the data edge; and
forming the sync impulse corresponding to the sync window and the data impulse corresponding to the data window.
