摘要： A plotter device measures movement distance of a moving body along with other device belonging to the same network, in which only of the devices belonging to the same network functions as a master, and a device other than the master functions as a slave. This plotter device includes a measurement component, a communication component, and a calculator. The measurement component adds the movement distance while the plotter device is functioning as the master to the master movement distance of the plotter device, and does not add the movement distance while the plotter device is functioning as the slave to the master movement distance of the plotter device.

摘要： A DDS achieved in size and cost reductions by removing a ROM for storing a table and the like and suppressing an operation amount is provided. A DDS includes an NCO, a DAC, and a BPF. The NCO outputs a sawtooth wave. The DAC converts either one of the sawtooth wave outputted from the NCO and a triangle wave signal converted by a waveform converting circuit based on the sawtooth wave, from a digital signal into an analog signal. The BPF receives the signal converted into the analog signal by the DAC and extracts a sine wave at a predetermined frequency from the inputted signal, by allowing a signal at a frequency within a fixed range to pass therethrough.

摘要： To achieve an unnecessary signal identifying device that can accurately identify an unnecessary signal from a reception signal. Correlators 321-32n correlation process the reception signal and a replica code at every predetermined timing, and output correlation data. Each of Buffers 331-33n stores a predetermined sampling number of the correlation data along a code phase axis, and output them to FFT processors 341-34n and a identifier 35. Each of the FFT processors 341-34n FFT processes the predetermined sampling number of the correlation data to acquire a frequency spectrum, and output it to the identifier 35. From a correlation data series on the code phase axis and the frequency spectrum, the identifier 35 acquires a property of the correlation data for a two-dimensional range of the code phase axis and a frequency axis, and identifies the signal with the property coinciding matching with characteristics of the unnecessary signal as the unnecessary signal.
