Claim 12:
13. A signal processing method of a light detection and ranging (LIDAR) system, comprising:
outputting a number of output pulses to a target object;
receiving a plurality of input pulses corresponding to the number of output pulses;
converting the plurality of input pulses of a continuous signal form into discrete signal forms; and
encoding amplitude information of the plurality of input pulses converted into the discrete signal forms,
wherein converting the plurality of input pulses of the continuous signal form comprises converting the plurality of input pulses into the discrete signal forms by a plurality of comparators to which variable reference voltages having different voltage values are applied,
the encoding the amplitude information comprises:
a first comparison step of comparing a voltage of each of the plurality of input pulses and a first variable reference voltage;
a second comparison step of comparing the voltage of each of the plurality of input pulses and a second variable reference voltage when a falling edge does not occur in the first comparison step; and
an inversion step of inverting a current data value and transferring the inverted data value to a register when a rising edge occurs in the second comparison step, and

the method further comprising adding or deleting the second comparison step and the inversion step according to a number of comparators comparing the voltage of each of the plurality of input pulses and the variable reference voltage.
