摘要： A system and method are provided for minimizing data-dependent power variations. The system and method can include summing an input with a dither signal, processing the summed signal, and substantially removing the effects of the dither signal from the output. The output is an approximation of processing to the input alone, while certain aspects of processing activity, such as temperature changes and current draw, are less dependent on input values. Variations in data-dependent activities are thus reduced. The effects of the dither signal may be removed by equivalently processing the dither signal alone, and using that result as a compensating signal to cancel components of the processed signal that result from the presence of the dither signal.

摘要： An improved method of configuring digital information in a recording storage media so as to significantly increase the information storage capacity of the media, and the media containing such configured digital information are disclosed. Information containing markers are arranged and configured along tracks in the media in a manner such that markers of adjacent tracks are offset relative to one another. Inter-track spacings of arcuately shaped tracks on a storage media are progressively reduced as a function of the radial spacing of the tracks from their center of curvature, further increasing the marker packing density. Return to zero pulsed modulation schemes are employed to maximize the amount of information recorded in a given number of marker locations. Drive means for reading digital information configured on storage media according to the principles of this invention are provided.

摘要： In one representative embodiment, scaling factors and delay values associated with respective analog-to-digital converters (ADCs) of an interleaved ADC are stored in memory. As a digital sample from the interleaved ADC is received, a respective amplitude scaling factor is retrieved from memory and applied to the digital sample. Preferably, a first order correction is then applied to the amplitude corrected-sample. The first order correction estimates the derivative using the current amplitude corrected sample and at least one additional amplitude corrected sample. The derivative is multiplied by an estimate of the respective timing delay associated with the particular sample. The corrected amplitude value is added to the multiple of the derivative and the timing delay to form the fully corrected digital sample.

摘要： Outputs of a linear phased array antenna can be employed for emitter field sorting, i.e., providing an indication of the frequency and angle of arrival of signals from a plurality of radiation sources, through the use of a two-dimensional optical processor that does not require a mechanism for correcting for acoustic spreading in a multi-channel Bragg cell. In effect, the multi-channel array of transducers of a Bragg cell forms a composite N-channel transducer the width of which is N times the spacing between channels. For a CW radiation source, the signal received by each array element undergoes an incremental phase shift associated with the tilt of the phase front across the array. When these signals are used to drive respectively adjacent transducers of a multi-channel Bragg cell, the acoustic effect within the bulk is equivalent to that of driving a large composite transducer with a constant frequency signal. This larger size of the effective composite transducer provides significantly reduced divergence of the composite acoustic wave, while the linear phase shift across the transducer results in a tilting of the composite acoustic wave. The two-dimensional acoustic wave modulation of a light beam passing through the Bragg cell is then imaged in the transform plane of a downstream Fourier transform lens, so as to produce a two-dimensional Fourier transform of the Bragg cell. In the transform plane there is provided a frequency display in the horizontal (parallel to the direction of travel of acoustic waves in the Bragg cell) direction and an angle of arrival (azimuth angle) display in the vertical direction. Multiple radiation sources at different locations may be processed independently through superposition.

摘要： Linearization of a closed-loop acousto-optic modulation system is maintained over a uniform closed-loop bandwidth that is independent of the output light intensity level through the use of a compensating square-root function generator which employs the third quadrant characteristic of a MOSFET. The MOSFET may be connected as the feedback impedance of an operational amplifier which provides the square-root gain control function for complementing the non-linearity of the acousto-optic modulator. By utilizing the third quadrant characteristics of the source-to-drain voltage relative to the drain current of the MOSFET, the square-root function generator has a transfer function which insures that a linear relationship between modulator output light intensity and input signal current can be obtained irrespective of light intensity.In accordance with a preferred embodiment of the present invention, the operational amplifier of the square-root function generator may be supplied with an offset voltage in order to insure that the desired square-root transfer function can be attained regardless of differences in the manufactured characteristics of the field effect transistors that may be used. Temperature compensation circuitry may also be adopted as part of the square-root gain control component of the system to counteract the temperature sensitivity of the MOSFET's square-root current-voltage characteristic.

摘要： A digital-to-analog conversion system comprises a digital input, a digital-to-analog converter and a modified digital signal generator. The digital-to-analog converter has a conversion frequency and is subject to a periodic error having a periodicity equal to that of an N-th sub-harmonic of the conversion frequency, where N is an integer. The digital input is operable to receive a digital input signal. The modified digital signal generator is interposed between the digital input and the digital-to-analog converter and is operable in response to the digital input signal to generate a modified digital signal. The modified digital signal comprises a dynamic digital mitigation component that mitigates the periodic error of the digital-to-analog converter.

摘要： A digital filter and method of filtering frequency translate or shift a spectrum of a digital input signal and further filter a translated signal to reduce or attenuate frequency components in the spectrum of the input signal. The digital fitter includes first and second translators and a first filter. The first filter is connected between the first and second translators and is centered approximately at direct current (DC). The digital filter may further include a second filter, a third translator connected to an output of the second filter, a complex local oscillator connected to an input of each translator, and a complex-to-real converter connected to an output of the third translator. The method includes frequency translating the digital input signal and separately frequency translating a first translated signal after the first translated signal is filtered to produce a second translated signal.
