Abstract:
1. A method for decomposing a high frequency multiphase signal to one or more low frequency digital words, the method comprising: receiving an incoming signal, the signal having a first phase and a second phase; decomposing the first phase of the incoming signal into a first alpha signal and a first beta signal; decomposing the second phase of the incoming signal into a second alpha signal and a second beta signal; processing the first alpha signal at a first logic unit to provide a first output signal, the first output signal preserving a rising edge of the first phase signal; processing the first beta signal at a second logic unit to provide a second output signal, the second output signal preserving a falling edge of the first phase signal; processing the second alpha signal at a third logic unit to provide a third output signal, the third output signal preserving a rising edge of the second phase signals; processing the second beta signal at a fourth logic unit to provide a fourth output signal, the fourth output signal preserving a falling edge of the second phase signal; and combining the first output signal with the second, third and fourth output signals to form a combined signal; wherein the combined signal has a frequency which is a fraction of the incoming signal frequency.
