Abstract

An electronic timing generator with a plurality of outputs being defined by a particular relationship with the phase angle of a periodic input signal. Each period of the input signal is divided into a plurality of "time slices" uniquely identified by a numerical value. Each time slice number is applied as a context or address to a storage circuit and the corresponding data retrieved from the storage circuit is used to produce the corresponding output signals through a latching circuit. Each context may have associated with it one retrieval step or several retrieval steps. The storage circuit permits the entry of an image input from a second input source that may be a sophisticated programmable computer or simply a plurality of manually operable switches. Or the second source may be merely an image permanently stored in the memory. The electronic timing generator has particular application to a wide variety of devices including stage lighting systems, internal combustion engines, electric power generators and other cyclic systems wherein external factors affect the desired output and the real time moment by moment exhaust of pollutants and contaminants.
