Abstract: A data driver in a flat panel display comprises: a latch for receiving a data signal in series, and for outputting the data signal in parallel; and a digital-to-analog (D/A) converter for converting the digital signal outputted by the latch into an analog signal. The D/A converter receives a reference signal having a voltage level which varies with time and outputs an output signal corresponding to a voltage level of the reference signal at a point in time when the reference signal has a voltage level the same as that of the digital signal. Thus, gradation of a data signal is represented on the basis of a reference signal, and therefore the gradation of the data signal is compensated by converting the reference signal, thereby compensating the gradation of the data signal without using an additional device. The latter functions correspond to the steps of a data converting method.

Abstract: An apparatus and method for detecting a pilot signal in a mobile communication system are provided by which the processing time taken to demodulate a traffic channel based on a channel estimation result can be reduced, and thus, the size of a buffer for buffering signals until the presence of a secondary/auxiliary pilot signal is detected can also be reduced. The apparatus includes a first channel estimator for estimating a channel for a noise component of a pilot symbol received by a first receiver, a second channel estimator for adding a pilot symbol received by a second receiver and the pilot symbol received by the first receiver and estimating a channel for a noise component of the added pilot symbol, an energy detector for detecting an energy value of a pilot symbol using result values output from the first and second channel estimators, and a comparison and determination unit for determining whether or not there is a secondary/auxiliary pilot signal by using the detected energy values.
