Arrangement for compensating amplitude and phase distortion of an electric signal

Claim 1

A DIRECTIONAL COUPLER EMPLOYED IN SYSTEMS WHICH COMPENSATE THE DISTORTION OF AN ELECTRIC SIGNAL WAVE COMPRISING: FIRST AND SECOND TRANSMISSION LINES HAVING CHARACTERISTIC IMPEDANCES ZO AND MZO; SAID SECOND TRANSMISSION LINE BEING OF A PREDETERMINED LENGTH; SAID FIRST TRANSMISSION LINE BEING AT LEAST AS LONG AS SAID SECOND TRANSMISSION LINE; FIRST AND SECOND TERMINATING IMPEDANCES ZO AND MZO EACH BEING RESPECTIVELY CONNECTED TO ONE END TERMINAL OF SAID FIRST AND SECOND TRANSMISSION LINES; THE REMAINING END TERMINAL OF SAID FIRST TRANSMISSION LINE RECEIVING SAID ELECTRICAL SIGNAL WAVE; THE REMAINING END TERMINAL OF SAID SECOND TRANSMISSION LINE PROVIDING THE DESIRED OUTPUT SIGNAL; A PLURALITY OF NON-INDUCTIVE RESISTORS COUPLING SAID FIRST AND SECOND TRANSMISSION LINES; EACH OF SAID RESISTORS HAVING THEIR END TERMINALS CONNECTED TO SAID FIRST AND SECOND TRANSMISSION LINES; THE POINTS OF CONNECTION ALONG SAID FIRST AND SECOND TRANSMISSION LINES BEING ARRANGED AT EQUALLY SPACED INTERVALS SO AS TO SPACE SAID RESISTORS APART BY A DISTANCE 1/4N WAVELENGTH OF THE SUBSTANTIAL CENTER FREQUENCY OF SAID ELECTRICAL SIGNAL WAVE INTERCONNECTING SAID FIRST AND SECOND TRANSMISSION LINES.
