Abstract: In illustrated embodiments, at least one analogue shift register has a number of parallel inputs and one series output. A number of individual evaluating circuits receive the signal to be filtered and supply respective output quantities of charge equal to the product of the difference between the relevant signal value and a predetermined minimum or maximum value, and a respective individual evaluation factor. The output of each evaluating circuit can be connected via a switching element to an associated parallel input. The capacity of every storage position of the shift register is at least such that it is always able to accommodate the maximum quantity of charge supplied by the preceding storage position, and when the storage position has a parallel input, can additionally accommodate the maximum quantities of charge supplied by the associated evaluating circuit (s). Various modifications are disclosed for reducing the space requirement of a transversal filter when implemented, for example, as a CCD.

Abstract: A TDM/PCM switching network comprising a plurality of time and spatial switching circuits associated with different groups of TDM lines. The present invention is primarily concerned with the manner in which these time and spatial switching circuits are arranged to transmit PCM words from a particular origin route to a given destination route. The spatial switching circuits each include intermediate storage means having a plurality of individual storage positions which are individually assigned to a predetermined destination route in the switching network. Time slots on the TDM lines are divided into a plurality of time intervals each associated with a particular TDM line of the group of TDM lines connected to the time circuit. Time slots are transmitted to the spatial switching circuit which includes a holding storage for allocating the PCM signal contained in the time intervals of a particular time slot to an intermediate storage according to the time slot or time channel itself. The PCM signals are connected to the appropriate destination TDM line through a demultiplexer/multiplexer device and other spatial switching circuits.

Abstract: A pulse code modulation, time division multiplex (PCM/TDM) switching network is used in tandem exchanges for connecting receive and transmit trunks and for allocating receive time slots to time slots to be used on the transmit trunks is described. A storage is assigned to each pair of associated receive and transmit trunks. The storage includes storage areas which are selectively connectable to the associated pairs of trunks. A storage location used for a call is seized sequentially during each sampling pulse frame with data coming in over the receive trunk as well as with data outgoing over the transmit trunk. Inputs and outputs of the storage areas not connectable to the trunks are combined with coordinated inputs or outputs of the storage areas of other similar storages. Information output and input likewise takes place selectively over the combined inputs or outputs.

Abstract: A telecommunication switching network having a multistage reversed trunking arrangement and switching on a four wire basis is described. A number of single channel subscriber lines is connectible to a first switching stage. The number of subscriber lines equals the product of e . v . g where g equals the number of groups into which the subscriber lines are divided, v equals the number of subgroups into which each group is divided and e equals the number of terminals in each subgroup, or the number of termination coupling circuits in that group. A time division multiplex trunk having a number z time slots connects each subgroup of termination circuits to a second switching stage. A total of z . v . g connection channels extend between the first and second switching stages. The first switching stage includes conductor cross switching apparatus for error-free switching.

Abstract: A time division multiplex (TDM) switching network having TDM switching units which, through time position conversion, selectively assign time slots on connected TDM lines is described. The TDM lines are formed into a matrix, the crosspoints of which are connected by the TDM aforementioned switching units. The TDM switching units have a fixed traffic capacity which is defined by the maximum number of time slot connections that the switching units are capable of making between the TDM lines connected thereto. The fixed traffic capacity of the switching units is dependent on the size of the TDM switching network but smaller than the maximum rated traffic capacity of the TDM lines. As a result, in the event the TDM switching network is expanded, the fixed traffic capacity of the additional TDM switching units can be progressively reduced.
