    摘要: A digital modulating/demodulating apparatus includes a demodulator for demodulating a modulated signal into a demodulated positional signal in response to a receipt of the modulated signal, a decoder for decoding the demodulated positional signal into a digital signal of N bits. A previous signal point on the constellation plane is defined by a previous demodulated positional signal and a current signal point on the constellation plane is defined by a current demodulated positional signal. The decoder outputs a digital signal of N bits, based on en amplitude and a phase of the previous signal point and the amplitude and the phase of the current signal point.

    摘要: A chip-type filter has a laminated body formed by stacking a plurality of capacitor elements, a pair of positive electrode terminals, a pair of negative electrode terminals, insulating outer resin, and an inductor section. The laminated body includes capacitor elements in a first group and capacitor elements in a second group, the positive electrode sections in both groups are disposed on the opposite sides with respect to the negative electrode sections. Positive electrode terminals are electrically connected to the positive electrode sections of capacitor elements in the first group and those of capacitor elements in the second group, respectively. Negative electrode terminals are electrically connected to the negative electrode sections in the laminated body, and are disposed at both ends of the direction crossing the connecting direction between the positive electrode terminals. The inductor section is insulated from the negative electrode sections and couples the positive electrode terminals.
