Abstract: Disclosed is a distortion-compensation apparatus that can reduce the storage space for storing coefficients required for distortion-compensation calculation, and can accurately execute distortion compensation. Distortion-compensation apparatus (100) compensates for distortion of an output signal from a predetermined circuit by predistortion in which an input signal is preliminarily multiplied by a coefficient. First multiplication section (200c) of distortion-compensation apparatus (100) multiplies an input signal by a first coefficient selected from coefficient candidates in accordance with the input signal; second multiplication section (201c1 to 201cm) multiplies a delay signal of an input signal by a tap coefficient; and adding section (202) outputs a signal obtained by adding together an input signal multiplied by the compensation coefficient and the delay signal multiplied by the tap coefficient to the predetermined circuit.

Abstract: In a digital PLL circuit outputting a clock signal with a frequency obtained by multiplying a frequency of a reference signal by a frequency command word (a frequency ratio), an RPA serially adds a frequency command word containing a fractional component. An output of the RPA is input to a minute phase error generator. The phase error generator generates a plurality of threshold values close to an actual amplitude value of the reference signal based on the fractional portion of the serially added value of the frequency command word, calculates the amplitude value of the reference signal and a phase error of the reference signal corresponding to the amplitude value based on the threshold values, and calculates a minute phase error between the reference signal and the output clock.

Abstract: In a digital PLL circuit, a phase comparison circuit counts the numbers of transitions of a reference clock and an oscillation clock, sets a time taken until the number of transitions of the reference clock reaches a reference count value as a phase comparison time period, and detects, as a phase error value, a difference between a target count value, obtained based on a magnification value of a desired oscillating frequency with respect to the frequency of the reference clock and the reference count value, and the number of transitions of the oscillation clock in the phase comparison time period. A smoothing circuit smoothes the phase error value. A digitally-controlled oscillation circuit controls the frequency of the oscillation clock in accordance with the phase error value smoothed by the smoothing circuit.

Abstract: A sheet processing apparatus has a process tray onto which a sheet is stacked, an aligning member that conveys the sheet toward a sheet edge regulating member in a contact state in which the aligning member, the sheet edge regulating member regulating the edge of the sheet, and a switching member that switches a state of the aligning member between the contact state where the aligning member is in contact with the sheet, and a non-contact state where the aligning member is spaced apart from the process tray. While the sheet on the process tray is being conveyed toward the sheet edge regulating member by the aligning member, the switching member switches the aligning member from the contact state to the non-contact state, and further switches the aligning member from the non-contact state to the contact state.

Abstract: A filter circuit includes two parallel digital filters, a DAC, and an LPF. The DAC includes two parallel decoders, a parallel-to-serial converter, a switch driver, and a switch. A PLL circuit supplies a reference clock to the DAC. A frequency divider provided in the DAC divides the frequency of the reference clock by two, and supplies the half frequency clock to a parallel processing section (the two decoders and the parallel-to-serial converter) of the DAC and the two digital filters. This makes it easy to secure a timing margin, permitting use in high-speed communication on the order of several GHz.
