    Abstract: THIS APPLICATION DESCRIBES A SYSTEM OF PULSE DETECTION AND REGENERATION WHICH INVOLVES THE STEPS OF (1) COMPARING THE RECEIVED SIGNAL WITH A PLURALITY OF LOCALLYGENERATED, PREDISORTED SIGNALS REPRESENTING ALL POSSIBLE PULSE TRAINS, (2) ISOLATING THE ONE COMPARISON SIGNAL WHICH IS INDICATIVE OF THE "CORRECT" LOCALLY-GENERATED PULSE TRAIN, (3) IDENTIFYING THE REFERENCE GENERATOR THAT PRODUCED THE "CORRECT" PULSE TRAIN, AND (4) TRANSMITTING AN UNDISTORTED REPLICA OF THE DISTORTED RECEIVED SIGNAL IN RESPONSE TO SAID IDENTIFICATION.

    Abstract: To provide discrimination between harmonically related signals, the conventional short-circuited and opencircuited transmission line choke is modified by dividing it into two dissimilar regions. In the short-circuited choke, the first region, adjacent to the input end, is loaded by means of a first dielectric material having a first dielectric constant Epsilon 1. The second region, constituting the balance of the line, is loaded by means of a second dielectric material having a second dielectric constant Epsilon 2, where Epsilon 2 is greater than Epsilon 1. In the open-circuited choke, Epsilon 2 is less than Epsilon 1. In either case, the desired input impedance characteristic of the choke is realized by adjusting the magnitudes of Epsilon 1 and Epsilon 2, and the lengths of the two regions.

    Abstract: PHASE-LOCKING OF ONE OR MORE SEPARATE POWER SOURCES IS A CONVENIENT METHOD OF AMPLIFYING FREQUENCY MODULATED SIGNALS OR COMBINING THE OUTPUTS OF A PLURALITY OF SIGNAL SOURCES. CERTAIN TYPES OF DEVICES, HOWEVER, DO NOT SUBMIT TO PHASE-LOCKING. IN SUCH CASES, THE SOURCES ARE USED TO PUMP A PARAMETRIC DEVICE, AND THE PARAMETRIC DEVICE IS PHASE-LOCKED. IN THIS WAY, PHASE COHERENCY IS INDUCED AMONG THE OUTPUTS OF ONE OR MORE SIGNAL SOURCES, WHILE THE SOURCES THEMSELVES ARE OPERATED IN THEIR PREFERRED, FREE-RUNNING STATE.

    Abstract: This application describes an impedance-matching network comprising two transformers having turns ratios, 1:N and 1:M, where N and M are rational numbers. The first of these transformers senses the signal current flowing in the signal wavepath and induces a secondary current that is proportional thereto. The secondary current, thus induced, energizes the second transformer which injects into said wavepath a component of current that is proportional to the signal current by a factor equal to the product of the turns ratios of the two transformers. When at least one of the two transformers is a two-winding transformer, the effective turns ratio of this network is given by 1:1 + OR - 1/(NM), where the sign ( + OR - ) is determined by the manner in which the transformers are connected. When two, single-winding transformers, such as autotransformers, are used, the effective turns ratio is given by 1: ((N-1)/N + OR - 1/MN).

    Abstract: A feedback amplifier is disclosed wherein two trifilar transformers are used to couple into and between a main signal amplifier and an error amplifier. The signal source is connected in series with one winding in the main amplifier transformer and one winding of the error amplifier transformer. A second winding of each transformer is connected, respectively, to the input port of its associated amplifier, while the output from each amplifier is connected to the third winding of the other''s transformer. Advantageously, the input impedances of the main amplifier and the error amplifier are much less than the driving source impedance, while their output impedances are much greater than the source and load impedances. This permits the use of small, simple coupling transformers having very few turns. As a consequence, the resulting feedback network is exceedingly broadband, and the feedback delay correspondingly small.
