摘要： A filter comprising a charge-coupled device having a first group of cells weighted according to a recurring filter law and having a second group of cells weighted according to a non recurring filter law. The cells of the first and second groups are interposed alternately and the displacement of the charges under these cells is carried at frequency twice that of the sampling rate of the input signal. Thus the effects of transfer inefficiency are suppressed without added hardware.

摘要： The present invention relates to telephony switching circuits which are used in electronic automatic exchanges operating on the time-division multiplex system known as PCM. According to the invention, a spatial and time switching circuit comprises a plurality of registers for memorizing the binary words of an input PCM frame, a plurality of time-slot registers for memorizing the output time-slots of the binary words, means for reading out the binary words registers when the time-slots defined by the time-slot registers occur, means for spatially switching the binary words thus readed out onto a plurality of output PCM links, and means for filling the output time-slots into the time-slot registers and selecting the output PCM links.
