摘要： A signal obtained by optically scanning a bar code is subjected to differentiation to obtain differential data. Peak-to-peak distances are calculated from the differential data. When a peak-to-peak ΔTx distance is y times of a basic width, frequency f(x,y) will be, f(x,y)=y/ΔTx. A frequency map is prepared from the frequencies calculated. Transition routes in which one frequency each is selected from each of the peak-to-peak distances, are formed. A transition route for which an error in frequencies is the least is taken as the most suitable transition route. An average of the frequencies included in the transition route is taken as a frequency f0 of the basic width.

摘要： An I/O cell (101) becomes an output state according to a burn-in test mode signal M in a burn-in test and the output of a port output signal setting register (106) is selected in an output signal selecting circuit (105). An instruction for periodically alternately setting “H” and “L” in the port output signal setting register (106) is written in test ROM (103). According to this circuit configuration, in burn-in, “H” and “L” are alternately output from the I/O cell (101) and appropriate stress can be applied to the I/O cell (101).

摘要： A transfer process in which, an original vector signal is precoded to an intermediately-precoded vector signal, and the extended modulo operation is performed when the intermediately-precoded vector signal is located outside a predetermined extended-modulo limit area, and the precoded vector signal is transferred through a system having a predetermined filtering characteristic. From the transferred vector signal, the original vector signal is detected, based on a relationship between the vector components of the original vector signal and the transferred vector signal.

摘要： A modulator and demodulator apparatus for use with a network is provided. The modulator and demodulator apparatus comprises a modulation section which includes a timing phase discrimination section for receiving, as an input signal thereto, a demodulation vector signal sampled into a digital value and discriminating to which one of a plurality of regions of a discrimination plane the phase of the input signal belongs. The timing phase discrimination section supplies, as an input to a next processing stage, a rotation vector obtained by rotating an input vector, moves the rotation vector to a quadrant which includes a reference discrimination region of the discrimination plane and performs, when the vector after the movement is not in the reference discrimination region, a predetermined calculation. When the vector after the movement comes to the reference discrimination region, another calculation is performed. This discriminates a timing phase of the input vector from the result of the calculation.
