Abstract
A method for processing a sinusoidal carrier frequency signal includes generating a series of samples by sampling the carrier frequency signal at a system sampling rate until a wrap up sample is yielded. The wrap up sample position is within a predetermined distance of an end of a cycle of the carrier frequency signal and, the series of samples constitute a digital representation of the cycle of the carrier frequency signal. A position of each of the series of samples is adjusted by an amount proportional to the wrap up sample position from the cycle end and the adjusted samples are stored in memory.
Claims8
A method for processing a plurality of sinusoidal carrier signals at different frequencies for subsequent use in a data transmission system having a system sampling rate and a jitter tolerance, comprising:
- for each different frequency:
- generating a series of samples by sampling a respective one of the plurality of sinusoidal carrier signals at the system sampling rate until a wrap up sample is yielded, said wrap up sample position being within a predetermined distance of an end of a cycle of said respective carrier signal, wherein the series of samples comprise a digital representation of at least one cycle of the respective carrier signal and said predetermined distance is representative of the jitter tolerance;
- adjusting a position of each of said series of samples by an amount proportional to said wrap up sample position from said cycle end;
- and
- storing said adjusted samples in memory.
