Description: |
| Original application filed 24 Oct., 1957, now Patent No. 3,258,667, dated 28 June, 1966. Divided and this application filed 08 Oct., 1965. This application is a division of co-pending application filed 24 Oct., 1957 (and issued on 28 June, 1966 as U.S. Patent 3,258,667), such co-pending application being a continuation-in-part of the now abandoned application filed June 23, 1955.
Abstract:
A phase shift decoder in which digital intelligence in the form of discrete signals or electrical pulses is converted into analog variations in the form of a changeable or variable phase between two recurring waves. The decoder may accept randomly occurring time-space input pulses and create corresponding variations in the phase of the output waves from reference and information scaling channels having the same scaling ratio and normally receiving as inputs the same recurring master signals. The input pulses cause the response of the information channel to the master signals to be selectively increased or de- creased, thereby slightly to advance or retard the phase of the information channel output wave, relative to the output wave of the reference channel. The system disclosed insures that the randomly occurring information pulses are converted into pulses which are noncoincident with the master signals; and it acts to combine the master and information pulses into a stream which contains one more or one less pulse than the master pulses for each information pulse. It is to these latter aspects of what are called the "chronizer" and the "add-delete means" that this divisional application is directed, although the disclosure in the present case is substantially identical to that of the parent application identified below. |
