摘要： A comparison judgment circuit judges the level of a signal received, via a transmission line, from a second device which is a communication partner. An input/output terminal is connected to the transmission line. An attenuator circuit attenuates the voltage at the input/output terminal so as to generate an attenuated voltage. A level comparator compares the attenuated voltage with a predetermined threshold voltage, and generates a level judgment signal that corresponds to the comparison result. A protection circuit monitors the voltage at the input/output terminal or the attenuated voltage. When the voltage to be monitored deviates from a predetermined voltage range, the protection circuit forcibly cuts off or changes the voltage input to the level comparator.

摘要： A quadrature amplitude modulator is provided. An oscillator generates an in-phase carrier signal having a rectangular wave, a trapezoidal wave or a waveform similar to these, and a quadrature carrier signal, the phase of which is shifted by ¼ cycle relative to the in-phase carrier signal. A multi-level driver generates an in-phase modulated signal by amplitude modulating the in-phase carrier signal with an analog in-phase baseband signal having a discrete voltage level or current level in accordance with the in-phase baseband data. Likewise, the multi-level driver generates a quadrature modulated signal by amplitude modulating the quadrature carrier signal with an analog quadrature baseband signal having a discrete voltage level or current level in accordance with the quadrature baseband data The multi-level driver generates a modulated signal, the amplitude of which takes a discrete level, by combining the modulated signals together.

摘要： A comparison amplification unit compares a level of a signal in a positive line with that of a signal in a negative line and latches a comparison result. An input terminal of a first inverter is connected to the positive line and an output terminal thereof is connected to the negative line. An input terminal of a second inverter is connected to the negative line and an output terminal thereof is connected to the positive line. An activation switch selectively switches between a state where the activation switch outputs a power supply voltage to the other power supply terminals of the inverters that are connected in common, such that the comparison amplification unit is inactivated, and a state where the activation switch outputs the ground voltage such that the comparison amplification is activated. The comparator outputs a signal corresponding to at least one of the signal in the positive line and the signal in the negative line at a timing after the comparison amplification unit is activated.

The access unit accesses a user image stored in a recording medium, the processing unit forms a background image by reducing a color gamut of the user image, and the order sheet print control unit causes a printer unit to create an order sheet on which the background image is printed in a free rendering area. Also, the composition unit separates an area of a subject recorded by a user in the free rendering area from an image of the free rendering area read by a scan unit based on a color gamut of the background image and superimposing the area of the subject on the user image to thereby form a composite image. Finally, the composite print control unit causes the printer unit to print the composite image. A method that the system performs is also provided.
