  • Digital phase shifter
    Patent number: 5744992
    Abstract: A digital phase shifter phase shifts an input signal by a predetermined phase angle. A length of a cycle of the input signal is determined. Then an output signal is generated which is phase delayed from the input signal by a phase amount. The phase amount is approximately equal to the length of the cycle of the input signal multiplied by the predetermined phase angle.
