Abstract: A signal processing apparatus and method are provided. The signal processing apparatus adjusts the level of a certain signal from among sequentially input signals based on the levels of the signals, and the certain signal is one of signals input prior to the latest signal input to the adjusting unit. Accordingly, a storage cell is shared for lip-sync and AVC, resulting in reduced manufacturing costs, and enhanced stabilization of the signal and the rate of the stabilization of the signal.

Abstract: A coil block and an electronic device using the same are provided. The coil block includes a first coil, a second coil, a core having an intermediate layer for separating the first coil and the second coil from each other, and a shield for shielding the first coil, the second coil, and the intermediate layer, wherein the first coil and the second coil have the same winding direction. According to the coil block and the electronic device, the filtering can be performed without any inductance offset even if the PWM signal having the inversed phase or the same phase is inputted. Also, since two windings can be wound on to one core using a common coil, the cost and the size of the coil block can be reduced.

Abstract: An image apparatus and method for transmitting audio data are provided. Audio data of diverse formats are combined to form a single set of transmission data and transmitted in serial transmission over a single physical transmission line, so that convenient connection between A/V apparatuses can be provided.
