PULSE-SHAPING FILTERING DEVICE USED FOR MANY TRANSMISSION CHANNELS

摘要

PURPOSE: A pulse-shaping filtering device used for many transmission channels is used for a communication system having many transmission channels. CONSTITUTION: A shifting part shifts at least one channel data. Address signal generator receives an output signal of the shifting part, and generates the first and second address signals. A first storage part outputs a data which is stored in an address indicated by the first address signal transmitted from the address signal generator. A second storage part output a data which is stored in an address indicated by the second address signal transmitted from the address signal generator. Adder adds output data of the first and second storage parts. Demultiplexer performs a demultiplexing about an output signal of the adder. A signal distributor distributes an output signal of the demultiplexer. A pulse generator receives an output signal of the signal distributor, and generates at least one channel pulse. Accordingly, a pulse-shaping filtering device lowers a load on ROM, controls the ROM by using the fast clock.
