    Abstract: Methods and systems for impairment shifting may comprise receiving radio frequency (RF) signals in a receiver, downconverting the signals to baseband frequencies, and synchronizing the receiver to received signals. The frequency of a local oscillator (LO) may be adjusted to shift residual impairments to fall between desired baseband signals where they are least visible. The received RF signals may comprise analog, satellite, or cable, television signals. The LO frequency may be adjusted to configure the DC offset impairments to fall between luminance and chrominance harmonics. The LO frequency may be adjusted to configure I/Q imbalanced impairments from residual in-phase and quadrature mismatch of a picture carrier signal to fall about 300 kHz from a sound carrier signal in the analog television signals. The LO frequency may be adjusted to configure the I/Q imbalanced impairments from residual I/Q mismatch of a sound carrier signal to fall between luminance and chrominance harmonics.

    Abstract: A receiver includes a static I/Q calibration block and a correlation/integration block. The static I/Q calibration block is configured to substantially eliminate mismatches between in-phase and quadrature components of a portion of the spectrum having associated I/Q mismatches that are relatively frequency-independent. The correlation/integration block is configured to substantially eliminate mismatches between the in-phase and quadrature components of portions of the spectrum having associated I/Q mismatches that are relatively frequency-dependent in accordance with a pair of signals generated by the static I/C calibration block.

    Abstract: A spiral-wound membrane structure includes a central pipe and a film roll. The central pipe comprises a filter body and end covers separately connected to two ends of the filter body. A passage is formed in the center of the filter body, and two ends of the filter body are embedded in the end covers to be bonded on and sealed by the end covers. The film roll includes a guide cloth, a membrane and a mesh. The film roll is wound on the central pipe. The central pipe is directly made of a filter material, can be used as a pre-filter or post-filter, and can be matched with the film roll in the spiral-wound membrane structure to form a highly-integrated two-in-one composite filter. The composite filter can be mounted on a water purifier.

    Abstract: A device includes an analog front end for receiving a radio frequency (RF) signal. The analog front end contains a local oscillator that is tuned to a local oscillation frequency for down-converting the received RF signal to a first intermediate frequency (IF) signal. An analog-to-digital converter module converts the first IF signal to a digital baseband signal. The device also includes a digital processing unit for processing the baseband signal. The digital processing unit generates multiple clock signals from a reference oscillator having digitally adjustable reference frequency. The reference frequency and the multiple clock signals may interfere with the local oscillator and generate several frequency spurs that may fall within the bandwidth of the received RF signal. In a preferred embodiment, the digital processing unit adjusts the reference frequency by a certain amount so that the spurs do not fall within the RF signal bandwidth.

    Abstract translation: 一种装置包括用于接收射频（RF）信号的模拟前端。 模拟前端包含调谐到本地振荡频率的本地振荡器，用于将接收的RF信号下变频为第一中频（IF）信号。 模数转换器模块将第一IF信号转换成数字基带信号。 该装置还包括用于处理基带信号的数字处理单元。 数字处理单元从具有数字可调参考频率的参考振荡器产生多个时钟信号。 参考频率和多个时钟信号可能会干扰本地振荡器并产生可能落在所接收的RF信号的带宽内的多个频率杂散。 在优选实施例中，数字处理单元将参考频率调整一定量，使得杂散不落入RF信号带宽内。
