Generating sinusoidal signals and clock signals for frequencies of pattern in radio equipment involves multiplying two pairs of digital values together and adding results of multiplication

摘要

The method involves determining digital values described by the sinusoidal signal in that each two pairs of digital values are multiplied together and the results added. One pair of multiplied signals consists of the sine of the phase of the initial frequency at a conversion time and the cosine of the phase of a defined integral multiple of the raster frequency at the conversion time.
