Abstract: According to one embodiment of the invention, a method of sampling a signal is provided. The method includes receiving over a signal path an analog signal generated using a first clock signal by a first device. The method also includes sampling the analog signal using a second clock signal to generate a numeric representation of at least a portion of the analog signal. The frequencies of the first and the second clock signals differ from one another by a known amount. The method also includes communicating over the signal path the numeric representation for receipt by a second device. The signal path experiences loading and at least a majority of the loading of the signal path occurs between the sampler and the second device.

Abstract: A sin (x) or cos (x) computational generator is provided by a coarse and fine storage element sharing a common address bus with the coarse storage element storing full precision values for every Jth sample and said fine storage element storing correction values between the Jth samples. An arithmetic block operates on the output of the storage elements in response to addresses on the address bus to provide full precision values without storing full precision values.
