Abstract
A processor receives a first vector signal and a second vector signal from a circuit in response to the circuit receiving the first vector signal. The processor transforms the second vector signal from a time domain to a transform domain. The processor rotates the transformed second vector signal by a phase that is proportional to a time delay between the first and second vector signals to time-align the second vector signal to the first vector signal.

A method comprising:
- receiving, at a processor, a second vector signal from a circuit in response to the circuit receiving a first vector signal;
- transforming, at the processor, the second vector signal from a time domain to a transform domain;
- and
- rotating, at the processor, the transformed second vector signal by a phase that is proportional to a time delay between the first and second vector signals to time-align the second vector signal to the first vector signal.
An apparatus, comprising:
- a circuit to receive a first vector signal and generate a second vector signal in response to receiving the first vector signal;
- and
- a processor to transform the second vector signal from a time domain to a transform domain and rotate the transformed second vector signal by a phase that is proportional to a time delay between the first and second vector signals to time-align the second vector signal to the first vector signal.
A non-transitory computer readable medium embodying a set of executable instructions, the set of executable instructions to manipulate a processor to:
- receive a first vector signal and a second vector signal from a circuit in response to the circuit receiving the first vector signal;
- transform the second vector signal from a time domain to a transform domain;
- and
- rotate the transformed second vector signal by a phase that is proportional to a time delay between the first and second vector signals to time-align the second vector signal to the first vector signal.
