Abstract
PURPOSE: To perform signal selection, without the condition that no output is connected to any signal source even for a moment.
CONSTITUTION: The selection switch Ij is switched with the signals cj and rj and the confirmation signal aj is produced. The circuits 21 ... 2n take the logical sum of the switching confirmation signals a of n-1 sets, and the outputs y1 ... yn of each switch I are added 3 and output is made. When the signal cj is selected, the switching confirmation signal aj corresponding is operated as the off control signal for all less than rj and all except Ij are turned off. Since the outputs y1 ... yn are further added 3 and outputted, no moment is available when all the input signals are off and the signal is switched, and no switching is made without the presence of the switching confirmation signal.
