一种用于在一设备中自复数个(y个)信号选择复数个输入信号之设备具有一切换矩阵,该切换矩阵具有复数个n对1多任务器,其中每一n对1多任务器系指派给该y个信号中之n者之一不同输入集合,其中该等n对1多任务器中之每一者之每一输入信号集合之少于n个输入信号之一子集亦系另一n对1多任务器之一输入信号子集。

An apparatus for selecting a plurality of input signals from a plurality of y signals in a device has a switching matrix with a plurality of n to 1 multiplexers, wherein each n to 1 multiplexer is assigned to a different input set of n of the y signals wherein a subset of less than n input signals of each set of input signals of each of the n to 1 multiplexers is also a subset of input signals of another n to 1 multiplexer.
