First Claim

1. A method of maintaining a substantially constant phase relationship between transmitted energy at input and output terminals of an energy transmission network having energy storing delay elements producing a change in phase of the transmitted energy with respect to an input frequency thereof, including the steps of:
- dividing the energy storing delay elements into separate delay portions respectively producing changes in phase of the transmitted energy;
passing the transmitted energy through said divided delay portions in sequence to phase shift the transmitted energy;
doubling the input frequency of the transmitted energy at a reference phase angle; and
subtracting the input frequency of the transmitted energy passed through only one of the divided delay portions from the doubled frequency at said reference phase angle to reverse the phase shift of the transmitted energy passed through said one of the divided delay portions, whereby the phase shift effected by the other of the divided portions of the delay elements produces a net change in phase substantially equal to zero.

Abstract
The delay elements of a signal energy transmission network are divided into separate portions through which the transmitted energy is phase shifted in sequence by substantially equal amounts. A phase correction circuit reverses the phase shift through one of the divided delay portions by doubling the frequency of the signal at a reference phase angle and subtracting therefrom the input frequency of the signal phase shifted through said one of the divided delay portions in order to maintain a constant frequency vs. phase relationship.

- 11. In combination with an energy transmission network having energy storing delay elements between input and output terminals, means interconnecting divided delay portions of the energy storing delay elements for maintaining a substantially constant phase relationship between the transmitted energy at said input and output terminals, comprising means for transmitting the energy at an input frequency in series through said divided delay portions of the energy storing delay elements, frequency multiplier means connected in parallel with one of the divided delay portions for doubling the input frequency of the transmitted energy, and modulator means connected in series with the divided delay portions for subtracting the input frequency of the phase shifted transmitted energy from the doubled frequency to reverse the phase shift effected by only said one of the divided delay portions of the energy storing delay elements, said divided delay portions of the energy storing delay elements thereby producing a net change in phase substantially equal to zero.

19. A method of maintaining a substantially constant phase to frequency relationship between transmitted energy at the input and output terminals of an energy transmission network having signal delay elements, including the steps of:
- dividing the delay elements into separate delay portions through which the transmitted energy is phase shifted;
multiplying the input frequency of the transmitted energy prior to being phase shifted through one of the delay portions;
conducting the transmitted energy through a modulator following phase shift through said one of the delay portions with the frequency multiplied energy to produce a reverse phase shift of the transmitted energy at the input frequency; and
conducting said transmitted energy through the delay portions in series with the modulator between the input and output terminals.
- dividing the delay elements into separate delay portions through which the transmitted energy is phase shifted;
