    Abstract: An accuracy of a symbol modulation is accurately measured. A symbol modulation accuracy measuring device receives a signal to be measured from a signal output device, which outputs ideal symbol data generated by the ideal symbol data generating unit, and modulated by the symbol modulation unit according to a symbol modulation as the signal to be measured, via a memory, and measures the accuracy of the symbol modulation. The symbol modulation accuracy measuring device includes a symbol demodulation unit that demodulates the signal to be measured according to a symbol demodulation, and a modulation accuracy measuring unit that measures the accuracy of the symbol modulation based on a result of the demodulation by the symbol demodulation unit, and the ideal symbol data recorded in the ideal symbol data generating unit of the signal output device. The symbol modulation accuracy measuring unit acquires the ideal symbol data from the ideal symbol data generating unit via a digital interface or a recording medium.

    Abstract: A multi-input amplitude and phase measuring method is disclosed for measuring the amplitudes and the phases of measurement signals at a high speed and with a high degree of reliability. Measurement signals received by antennae are converted into IF signals with local signals of frequencies f.sub.LO +.DELTA.f, f.sub.LO +2.DELTA.f, f.sub.LO +3.DELTA.f, f.sub.LO +4.DELTA.f by a mixer and then added by an adder, whereafter they are multiplied by an analog multiplier to convert phase information of the measurement signals into signals of frequencies .DELTA.f, 2.DELTA.f, 3.DELTA.f, 4.DELTA.f. Then, the signals obtained by the conversion are A/D converted and Fourier transformed to determine a spectrum. Then, in order to eliminate an influence of phase displacement by band-pass filters, the local signals are added by an adder and multiplied by a local signal of frequency f.sub.LO by a mixer, and the resultant signal is A/D converted and Fourier transformed to determine a spectrum. A cross spectrum of the two spectra is calculated by a cross spectrum calculator to measure the amplitudes and the phases of the measurement signals.

The lightguide plate emits light received from the light source from the light-exiting surface. At least a part of the peripheral side surface is an inclined surface inclined relative to the light-exiting surface.

    Abstract: A backlight unit includes a planar light source member that has a light-emitting surface and that emits light having directivity in a perpendicular direction to the light-emitting surface. An optical member has a light-receiving surface opposed to the light-emitting surface of the planar light source member and a light-emitting surface opposite to the light-receiving surface. The light-receiving surface has a multiplicity of prisms. By the prism action, the optical member emits the light having directivity in the perpendicular direction from the planar light source member as light having directivity in at least two directions on opposite sides of the perpendicular direction. The directions of light directivity are changed by varying the apex angle of the prisms.
