Abstract: PURPOSE: To drive a liquid crystal panel without generating a flicker or noise on a screen. CONSTITUTION: An adding circuit 26 adds a noise component of an analog signal detected by a filter 24 to a reference voltage from a power source 16 and a phase adjusting circuit 28 adjusts the phase of the reference voltage to which the noise component is added. A circuit 12 holds the analog signal and outputs it to comparators 14a-14n. The reference voltage from the circuit 28 is divided by resistances 18a-18n and outputted as threshold voltages TVa- TVn to the comparators 14a-14n. The comparators 14 compares the inputted analog signal with the voltages TV and outputs a specific signal to an encoder 20 when the analog signal is larger than the voltages TV. The encoder 20 digitizes the signals from the comparators 14 and applies them to electrodes of the liquid crystal panel.

Abstract: PROBLEM TO BE SOLVED: To quickly perform acquisition and display of uniform resource locator(URL) contents. SOLUTION: In accordance with a user's activation operation, a contents collection part 162 compares a value of transmission rate (TD) inputted from a transmission rate monitoring part 182 with a threshold (C-α). When a condition of TD
