DIVERSITY SIGNAL SYNTHESIZER/DIVIDER

摘要

PURPOSE: A diversity signal synthesizer/divider is provided to distribute or synthesize each path-classified signal and block speech quality degrading cause such as the noise, loss, and delay of the distributed or synthesized signal. CONSTITUTION: An amplifier(25), a voltage adjustment variable phase shifter(22), and a voltage adjustment variable attenuator(23) are composed in N paths. The amplifier(25) maximally restrains a noise of a signal selected according to each path, and amplifies the level of the signal. The voltage adjustment variable phase shifter(22) adjusts a phase of the amplified signal as an optimum state. The voltage adjustment variable attenuator(23) adjusts the amplified level of the signal as the optimum state. An N-way synthesizing/distributing unit(21) synthesizes the signals inputted through the N paths, and outputs the synthesized signal to one path. The N-way synthesizing/distributing unit(21) distributes a signal inputted through one path to the N paths.
