Abstract:
1. A phase compensation circuit, comprising: a delay circuit receiving a composite input signal that exhibits a variable phase error, the delay circuit providing a plurality of selectable discrete delays; and a control circuit coupled to the delay circuit, the control circuit receiving a control signal whose value corresponds to the phase error associated with the composite input signal, the control circuit selecting one of the plurality of selectable discrete delays responsive to the control signal, wherein the selected delay is utilized to delay the composite input signal to provide a phase compensated composite output signal, and wherein the composite input signal is provided by a detector of an FM receiver whose input is coupled to an adaptive reception system (ARS) that receives a plurality of transmitted signals each through one of a plurality of antennas and provides a composite received signal to the input of the FM receiver, where the phase compensated composite output signal is provided to the ARS to phase align the plurality of transmitted signals received through the plurality of antennas; and an output buffer, the output buffer receiving and amplifying the delayed composite input signal.
