Abstract

A method for inputting and/or outputting signals having a selectable sample rate in a time-synchronized manner on a group of input and/or output channels of an electronic circuit includes: configuring each channel of the group at a standard sample period; synchronously initiating all the channels of the group at the standard sample period; detecting an entry for a modified sample period TPeriod of a first channel of the group; detecting a current counter value TCounter; configuring the first channel at the modified sample period; establishing a waiting time of TWaiting clocks in accordance with TWaiting=TPeriod−mod(TCounter, TPeriod), where mod (TCounter, TPeriod) denotes the division remainder from the current counter value TCounter and the modified sample period TPeriod; and initiating the first channel after the waiting time TWaiting.
