The method includes obtaining samples of the signal at at least two instants in time, and utilising the samples in a mathematical equation relating estimated offset frequency to the samples, wherein the mathematical ... 09/14/06 - 20060206551 - Frequency converter and methods of use thereof An all-digital frequency conversion apparatus is provided that achieves frequency conversion using a simple phase detector and integer and fractional phase feedback information from a digital oscillator output. In an embodiment, a target phase accumulator unit generates a target phase signal to the phase detector unit. The target phase accumulator ... 09/07/06 - 20060200512 - Signal generator provided with license control function and license control method thereof A signal generator has a signal creating and supplying unit which creates a test signal to be transmitted to a measurement object and a license management unit which manages a license of waveform data for use in creating the test signal by the signal creating and supplying unit. The license ... 08/24/06 - 20060190515 - Lookup table and data acquisition method Input data is divided into a plurality of blocks, and the blocks are corresponded to each address of the lookup table, and a block is divided into a plurality of sections according to the change of the output data, and at this time position information to indicates the boundary of ... 08/03/06 - 20060173944 - Exponential function generator An exponential function generator for generating an exponential generator to realize a linear region of about 60 dB required for the an ultra wide band system (UWB). Since the exponential function generator is implemented in a form of complementary metal oxide semiconductor fabrication (CMOS), compactness and operation control of the ... 06/22/06 - 20060136537 - Phase persistent agile signal source method, apparatus, and computer program product A phase persistent agile signal source method, apparatus, and/or computer program product provides a direct digital synthesizer (DDS) clock rate, provides a frequency tuning word (FTW) for a desired output frequency, provides a DDS update for a desired DDS update rate, provides an equivalent frequency least significant bit (LSB) for ... 06/08/06 - 20060123074 - Representing data having multi-dimensional input vectors and corresponding output element by piece-wise polynomials determining piece-wise polynomials which together would represent large data sets having multi-dimensional input vectors and corresponding output element. In an embodiment, a function/procedure/routine is recursively called/invoked to determine piece-wise polynomial is a data set cannot be entirely modeled by one polynomial. Another aspect of the present invention reduces the number ... 05/18/06 - 20060106905 - Method for reducing memory size in logarithmic number system arithmetic units A method for performing addition/subtraction on logarithmic number system (LNS) operands x and y that uses a single lookup table. The lookup table is populated by values of ln(1+exp(−α)) where α is an absolute value of difference of x and y. To perform an addition operation, the lookup table is ... 01/12/06 - 20060010184 - Superposition of waves using the cordic algorithm The invention relates to a method for creating a waveform composed by superposition of N waves using a Coordinate Rotation Digital Computer (CORDIC). To provide for generation of composite waveforms said CORDIC calculates within N calculating steps discrete values of said N waves, and said output of said discrete values ... 12/15/05 - 20050278403 - Numerically controlled oscillator and method of operation In one embodiment, the present invention is directed to a numerically controlled oscillator. The numerically controlled oscillator comprises: a phase accumulator for receiving an input digital word; and a phase to amplitude converter that is operatively coupled to the phase accumulator to receive a first phase signal and a second ... 06/23/05 - 20050138094 - Triggered dds pulse generator architecture A triggered DDS generator architecture accumulates a phase increment value in response to a DDS clock to generate phase accumulator values for addressing a waveform lookup table which contains a desired output signal. A time measurement circuit determines a time interval between the arrival of a trigger signal and a ... ### FreshPatents.com Support |
