Abstract: A cognitive function evaluation device includes: an obtainment unit that obtains utterance data indicating a voice of an evaluatee uttering a sentence as instructed; a calculation unit that calculates, from the utterance data obtained by the obtainment unit, a feature based on the utterance data; an evaluation unit that compares the feature calculated by the calculation unit to reference data indicating a relationship between voice data indicating a voice of a person and a cognitive function of the person to evaluate the cognitive function of the evaluatee; and an output unit that outputs the sentence to be uttered by the evaluatee and outputs a result of evaluation by the evaluation unit.

Abstract: An apparatus comprises input means, detection means and a selector, and automatically detects a kind of serial signal used in BER measurement. The input means receives at least two signals which include a data signal, and a clock signal having a period corresponding to one bit of the data signal. The detection means determines which one of the at least two signals is a clock signal or a data signal. The selector outputs the signal determined to be a clock signal from a clock signal terminal and outputs the signal determined to be a data signal from a data signal terminal.

Abstract: A bit error rate (BER) measuring apparatus is provided for measuring BER of an out-of-band tuner. The BER measuring apparatus generates a test signal for measuring the BER of the out-of-band tuner using a transport stream including a pseudo-random bit string (PRBS). In one embodiment, the BER measuring apparatus comprises a BER test signal generator that generates the test signal which includes a transport stream for transmission. The BER measuring apparatus also comprises a BER detector that detects the BER from a received test signal generated by the tuner in response to the test signal from the BER test signal generator. In one embodiment, the test signal generator comprises a PRBS generator that generates a first PRBS, and a transport stream framing circuit that frames the first PRBS into a transport stream form to generate the transport stream for transmission.

Abstract: A digital broadcasting signal generator improved in usability incorporates a TS generator section which generates a color bar TS signal, a digital modulation section which modulates the color bar TS signal in accordance with one digital broadcasting system selected from a plurality of digital broadcasting systems, and an up-converter section which converts the frequency of the color bar TS signal. The plurality of digital broadcasting systems are an ISDN system, a DVB system and an ATSC system.
