Abstract: An adaptive equalizer has an FIR filter for generating an equalized output signal by equalizing an RF input signal, a sign detector for detecting a sign of the output signal, an absolute value calculator for calculating an absolute value of the output signal, a level error detection part for calculating an error by using a sign and an absolute value, and a coefficient calculator for calculating coefficients of the FIR filter based on the error. The level error detection part detects a detection level of the output signal, the detection level which is one of reference values required by a channel characteristic model of a decoder provided with the output signal, and calculates the error which is the difference between the detection level and a real level of the output signal. Since the sign and the value of the signal are used for calculating the error, the reliability of the error calculation increases.

Abstract: A class D amplifier and a method of pulse width modulation are provided. The class D amplifier includes a sigma delta modulator, a reference signal generator, a pulse width modulator and an amplifier. The sigma delta modulator converts an M bit input signal into N bit pulse code modulation data (M and N are integers and M>N). The reference signal generator counts a system clock and generates an N bit reference signal having 2N data blocks in a sampling period of the pulse code modulation data. The pulse width modulator generates a plurality of pulse width modulation signals having at least two switching periods within the sampling period of the pulse code modulation data. The pulse width modulation signals have pulse widths varied based on a unit time interval of the reference signal. The unit time interval corresponds to one of the data blocks of the reference signal.

Abstract: Disclosed is a method for displaying a message in a folder-type mobile terminal including a main body, a sub-body foldably mounted to the main body, said sub-body having a first display mounted on an outer side and a second display mounted on an inner side thereof. Upon receipt of a message, while the sub-body is folded, the mobile terminal displays an indicator indicating receipt of the message on the first display. Upon receipt of a key input corresponding to a user's external display request, the mobile terminal determines whether the first display is set to a double-line display mode. If the first display is set to the double-line display mode, the mobile terminal slidingly displays the received message on a first line of the first display and fixedly displays a message received time and a caller's phone number on a second line of the first display. However, if the first display is not set to the double-line display mode, the mobile terminal then slidingly displays, in sequence, the received message, the message received time and the caller's phone number on the first display.
