摘要： An image-compression system, wherein the image consists of a planar array of data points having various brightness levels, comprises a transmitter and a receiver. The transmitter comprises an analog-digital converter, for converting input analog data into digital data. The cosine transform is taken of the incoming digital data to transform the data representing various brightness levels into the frequency domain. The various frequency data points are differentially pulse code modulated, thereby removing line-to-line redundancy, the output data being in parallel form. Timing circuitry is provided for controlling the timing of the various circuits. Circuitry is provided in a receiver for the modulating or decoding of the output signal of the transmitter.

摘要： A transform system provides a real-time implementation of the discrete Foer transform (DFT) of length N, the system being useful in sonar and radar signal processing. The input signal g.sub.n, 0.ltoreq.n.ltoreq.N-1, comprises a discrete signal, generally complex, of N samples.The system comprises an input for receiving the input signal g.sub.n and convolving in a first, input, convolver with a signal represented by the function e.sup.i.pi.n.spsp.2.sup./N , to result in a first modified signal at the output of the first convolver. Means are provided for generating the signal e.sup.-i.pi.n.spsp.2.sup./N. A multiplier receives the first modified signal and the signal e.sup.-i.pi.n.spsp.2.sup./N and multiplies these two signals its output being a second modified signal.A second, output, convolver, whose input is connected to the output of the multiplier, convolves the output signal from the multiplier with a signal represented by the function e.sup.i.pi.n.spsp.2.sup./N, to result in a discrete Fourier transformed (DFT) signal at the output. The output signal is generally a complex signal, having a real part and an imaginary part. One of the three chirps, represented by the two signals e.sup.i.pi.n.spsp.2.sup./N and the signal e.sup.-i.pi.n.spsp.2.sup./N, is multiplied by a factor of (1-i) either explicitly or in a summer for the corresponding complex operation in order to obtain the correct output phase.

摘要： Improved dynamic range resolution or accuracy analog to digital conversionses linear prediction. An open loop or feed-forward architecture passes an analog signal to a coarse or orthodox analog-to-digital converter that provides digital signals representing a most significant part of the output signal and offers them as inputs to a digital linear predictor whose digital output signal is reconverted to analog form and fed to an analog adder. An analog delay device may be used to receive the next analog sample and, after the proper delay (if needed), feed it to the adder where the difference between the analog predicted value and the analog signal is determined and passed to a subsequent coarse or orthodox analog to digital converter. A closed loop or feedback configuration receives the analog input signal data as well as a feedback predicted value in analog form and passes the difference to a coarse or orthodox analog to digital converter. A digital delay of the digital signal may be used to insure that the digital summing of prediction and digitized error signals occurs at the appropriate times. The recirculated predicted signal is converted to analog form (unless predicted via analog means) and subtracted from the analog input signal to provide an error signal output digitized to form low order bits that correspond in time with an output of high order bits generated by a digitized prediction signal. This arrangement improves the dynamic range, accuracy, resolution or number of resolvable signal levels in an analog to digital converter.

摘要： A frequency synthesizer, for use with a means for generating two sequences of electrical pulses, one sequence having a delay with respect to the other, comprises a surface acoustic wave (SAW) device, adapted to receive one of the sequences of electrical pulses from the generating means. The SAW device comprises a substrate, on the surface of which is disposed a first set of interdigitated electrodes. The electrodes receive the electrical pulses and tranduce them to acoustic waves, which traverse the surface of the substrate. The lengths of the electrodes are configured as a function of m, where m is defined by the relation m = R.sup.n mod P, where P is a prime number, R is a primitive root of P, and 1.ltoreq.n.ltoreq.P-1. A second set of interdigitated electrodes, approximately N-1 in number, is also disposed on the surface of the substrate, the electrodes of the first and second sets being parallel. The second set of electrodes is so disposed as to receive the acoustic waves generated by the first set of electrodes, and transduce them back to electrical signals, which are conducted on a set of leads connected to the electrodes. Means, adapted to receive pulses from the electrical pulse generating means, selectively receives the electrical signals from the second set of electrodes. The receiving means has as an output a signal whose frequency is determined by the order in which the signals are received from the second set of electrodes.

摘要： An acoustic communication method and system are disclosed for transmitting information through a well-bore drill string by using the acoustic noise inherently generated in the drill string by drilling operations as a "carrier" propagated therealong to be modulated by the information to be transmitted. In the drilling of wells, the action of the drill tool on the bottom of the bore hole creates acoustic noise within the drill string. Other suitable sources of "noise" are often present during "drilling operations", as broadly defined, even while bore drilling, as such, is suspended. This noise usually consists both of wide-band continuous acoustic energy and of narrow spectral lines of acoustic energy and is usually present in a variety of acoustic modes such as longitudinal and torsional acoustic waves. The detailed characteristic of this acoustic noise depends on the type of drill tool used, the drilling speed and the type of formation being drilled.When this inherently generated noise is modulated by an information containing signal at a signal-transmitting station, acoustic communication of information is possible while drilling is in progress, or, in some cases, while drilling as such is suspended. The communication occurs between the transmitting station and a signal-receiving station spaced along the drill string, using the intervening length of drill string between the signal-transmitting and signal-receiving stations as an acoustic transmission channel.

摘要： A sonar system that includes a new comb-like waveform constructed by modulating the tines of a comb spectrum according to a set of Hermite functions defining a Hermite Function Space (HFS), and a processing method that reduces the sidelobes of the ambiguity function associated with the normally-processed HFS comb waveform. Noise-limited performance remains high, because the waveform is designed to be power-efficient; range ambiguity is superior to the highly-rated sinusoidal frequency-modulation (SFM) waveform; and reverberation-limited performance is equal to or better than that offered by any other waveform designed for this purpose. The full Doppler sensitivity normally associated with pulsed CW can be realized by the application to HFS signals of the constrained, regularized deconvolution method of this invention. The deconvolutionally-processed Hermite-function comb waveform offers better reverberation-limited performance than does the triplet-pair comb waveform or any of its predecessors, while maintaining a noise-limited performance equal to the best of these.
