摘要： An apparatus is disclosed for inputting digital data on the output channel(s) of an audio subsystem in an audio device, without interfering with normal operation of the audio subsystem. The described circuit includes a resistive element in parallel with the expected load device, such as a headphone or speaker. The resistive element receives a modulated digital signal from a data source or a switch, and the instantaneous current through the resistive element due to the modulated digital signal is reflected in a current feedback mechanism of the audio subsystem. Demodulation logic retrieves the digital signal from the current measured by the current feedback mechanism. A capacitor is provided to prevent the current in the resistive element from the digital signal from impacting the average DC current that the feedback mechanism uses to evaluate the load device.

摘要： A method and system is disclosed tor designing a radio for down- converting RF signals to IF signals by sampling the signals in a round-robin sampling circuit and multiplying the samples by coefficients that are changed at a fixed rate equal to the rate of operation of each of the sampling circuits. The circuit is able to down-convert multiple channels simultaneously to adjacent positions in the IF band,, while rejecting unwanted image signals. The method and system avoids the difficulty and cost of directly digitizing the RF signal, allowing each component to operate at a greatly reduced speed. The coefficients are selected to provide the desired transfer function while keeping the output signal centered at a desired frequency.

摘要： A finite impulse response (FIR) filter having a differential output and capable of having negative coefficients, and a method of designing the filter, is disclosed. In contrast to the prior art, in which two output signals requires the use of two identical sets of impedance devices corresponding to the Fourier coefficients that create the desired response of the filter, the described method and system uses only a single set of impedance devices, and thus approximately one-half of the number of impedance devices used in the prior art. This is accomplished by appropriately selecting which resistors contribute to which output, so that a differential output may be obtained that is substantially the same as if impedance devices corresponding to all of the coefficients were used for each signal.
摘要翻译：公开了一种具有差分输出且能够具有负系数的有限脉冲响应（FIR）滤波器，以及一种设计滤波器的方法。与现有技术相比，其中两个输出信号需要使用与产生滤波器的期望响应的傅里叶系数对应的两组相同的阻抗装置，所描述的方法和系统仅使用一组阻抗装置，因此约为现有技术中使用的阻抗装置数量的一半。这通过适当地选择哪些电阻有助于哪个输出来实现，使得可以获得基本上相同的差分输出，如同对于每个信号使用对应于所有系数的阻抗器件一样。

摘要： An exemplary image sensor (100) comprises a photodetector (122,124,126,128) proximate to a pixel site (102), and a light meter (104) proximate to the pixel site configured to approximate an initial charge acquired by the photodetector at the end of a first integration period of a frame exposure period. A reset circuit (106) resets the photodetector if the approximated initial charge acquired by the photodetector exceeds a threshold. A readout circuit (108) detects a final charge acquired by the photodetector at the end of a second integration period of the frame exposure period. If the photodetector was reset, the readout circuit adjusts the final exposure to account for exposure prior to the photodetector having been reset.
