Abstract
A programmer produces binary output signals changing state during time intervals identified by a timing signal. Each output signal goes to the active or the inactive state, i.e. starts and ends during separate time intervals. The programmer includes a memory storing a start location and an end location for each output signal, respectively, holding the signal's start and end time intervals. The operation of a read unit for reading the values in these locations is determined by a control unit using an address generator so that the possibility of a change of state is examined for each output signal during each time interval. A comparator produces an identity signal if a first field of the read location has the same value as a first field of the time interval in which the reading takes place. A decoder changes the state of the output signal corresponding to the location for which the identity signal is produced. The control unit includes an indexing arrangement for representing the state of the output signal being examined in order to bring about reading of the start location of the output signal if it is inactive or of the end location of the output signal if it is active.
