IPC: H04J13/00
Filed: 1989-11-09
Abstract: PURPOSE:To eliminate an interference wave (disturbing wave) in an excellent way even when the interference wave of a remarkably large level is mixed in by providing an inverse spread circuit section comprising of a high pass filter(HPF), a phase shifter, a subtractor, a low pass filter(LPF) and 3 multipliers to a demodulation section. CONSTITUTION:A multiplier 3 in an inverse spread circuit section 15 of a demodulation section 20 applies inverse spread by multiplying a spread code with a spread spectrum signal to demodulate an information signal and to make an invaded interference wave spread. An HPF 17 eliminates demodulated information signal in an output of the multiplier 3. A multiplier 4 multiplies the spread code with the spread interference wave in an output signal of the HPF 17 to apply inverse spread thereby demodulating the interference wave. A phase shifter PS 18 inverts the phase of a spectrum component over or under a frequency where a main lobe of a spread code signal in a leakage component of a spread interference wave included in the output signal of the multiplier 4 is nearly a half in terms of energy. A multiplier 5 multiplies the spread code with an output of the phase shifter to apply spread to the interference wave again. A subtractor 6 subtracts an output of the multiplier 5 from the output of the multiplier 3.

Abstract: PURPOSE:To reduce a fall time of data signal to a ground voltage at a data pin located farther from a grounding voltage pad, by shortening a current-drive time of a switch means in a data generating means provided between the data pin for generating a given voltage and a power line connected to the pad. CONSTITUTION:A transient fall time of output data Dout generated from a data generating means 130 located farther from a ground voltage pad 104 is made short and at the same time, a fall time of another output data Dout from a data output means 130 located near to the ground voltage pad 104 is made the same as the former. Then, the access speed can not be slow because of a longer fall time of a data generating means 130 located farther from the ground voltage pad 104. Consequently, a time for generating a given voltage is made short even at a data generating means located farther from a pad, to which a given voltage is applied, and a state of undershoot or ringing is prevented even when a delay time is reduced at a delaying means in the data generating means 130.
