摘要： Distortion discrimination circuitry for digital radio receivers and corresponding methods are disclosed that accurately and efficiently discriminate distortion events, including impulse noise and multipath distortion events, to improve the quality of audio output signals. The distortion discrimination circuitry monitors and analyzes the demodulator output to determine when a distortion event has occurred and provides an appropriate indication signal for use by other circuitry within the radio receiver. More particularly, the distortion discrimination circuitry includes impulse noise circuitry that looks for high frequency noise in both the magnitude and multiplexed outputs of the demodulator to determine the occurrence of impulse noise distortion events. The distortion discrimination circuitry also includes multipath circuitry that looks for a drop-off in signal power between the multiplexed output of the demodulator and a moving average version of that same signal to determine the occurrence of multipath distortion events. In addition, stereo decoder circuitry modifies the audio output signals in response to indications of distortion events.

摘要： An improved metal center rotating anode x-ray tube is shown. The improved x-ray tube includes means for preventing the build-up of charge on the anode glass portion of the tube envelope where the glass flares by constraining the equipotential lines of the electric field in the vicinity of th eflare to parallel the flare surface. Parallelism may be achieved by (1) controlling the angle of the flare and sealing the flare directly to the metal section, (2) modifying the anode rotor to include a flare conforming to the glass flare, and (3) including a ground plane screen in the tube housing.

摘要： A receiver includes a memory, processing circuitry, and a memory protection unit. The processing circuitry is coupled to the memory, and has an input for receiving a radio frequency (RF) signal, and an output for providing an output signal at another frequency. The processing circuitry includes one or more independently powered components adapted to write data to the memory. The memory protection unit is coupled to the memory, and monitors a power supply voltage level corresponding to each independently powered component and, if the power supply voltage level changes during a power supply transition of an independently powered component in which the power supply voltage remains sufficiently large to power the independently powered component, to prevent write operations received from a corresponding one of the one or more independently powered components from occurring at least while the power supply voltage level is changing.

摘要： A radio frequency (RF) signal is received in a receiver, and various counts based on information from the signal can be obtained. Counts of a number of samples of the RF signal exceeding first and second thresholds can be accumulated during an accumulation window. From the first of these counts, it can be determined if the count exceeds a first metric corresponding to a first predetermined count value, and if so, a gain of an RF gain element can be reduced. From the second of these counts it can be determined if this count exceeds a second metric corresponding to a second predetermined count value, and if not, the gain can be increased.

摘要： An analog resistive touch screen is powered by a current source responsive to a stored digital control value. The current source is calibrated by comparing the excitation voltage across the touch screen to a desired voltage to produce a comparison signal, and adjusting the digital control value in response to the comparison signal so that the excitation voltage becomes substantially equal to the desired voltage. The power supply can therefore be easily constructed in a low-voltage CMOS integrated circuit having a minimal power consumption without sacrificing touch screen resolution. Preferably the comparison of the excitation voltage to the reference voltage is performed by an analog-to-digital converter that is later used in a normal conversion mode for digitizing the touch screen coordinates. Moreover, because the touch screen presents a different load resistance depending on whether a first resistive sheet is energized for measuring an X coordinate or a second resistive sheet is energized for measuring a Y coordinate, a separate calibration is performed for each of the two resistive sheets, and the digital control value from each calibration is stored in a separate register for selective retrieval to measure either an X coordinate or a Y coordinate.

摘要： An algorithmic converter system includes an algorithmic converter having a loop gain substantially less than two for converting an analog input signal to a redundant digital code; and a digital computation unit for converting the redundant digital code to a digital output signal by computing a polynomial of a radix, said radix being substantially equal to the loop gain, wherein the redundant digital code specifies coefficients of the polynomial. The redundancy extends the analog input conversion range with respect to the voltage reference of the algorithmic converter. Moreover, if the algorithmic converter has a maximum offset of V.sub.offmax, a reference voltage of V.sub.ref, and a loop gain less than 2/(1+V.sub.offmax /V.sub.ref), then loop offset will not cause differential nonlinearities. Nonlinearity is further reduced by digitally compensating for variations in the loop gain. The method includes measuring the loop gain of said algorithmic converter, and setting the radix of the computation unit equal to the measured value of the loop gain. Preferably the loop gain is measured by converting two reference voltages to obtain two sets of digits from the algorithmic converter, and employing a successive approximation technique that alternately computes an offset value and adjusts the radix. For the redundant signed digit (RSD) algorithmic converter, rapid convergence is obtained using a zero reference voltage and a non-zero reference voltage. For a conventional restoring (CR) algorithmic converter, however, positive and negative reference voltages are used.
