摘要： A circuit is provided for suppression of second-order intermodulation in a double-balanced mixer circuit. The circuit includes a duplicate transconductor element for duplicating AC current in a transconductor pair of the double-balanced mixer circuit. A fundamental cancellation element cancels a fundamental component of an AC current of the duplicate transconductor element, while preserving a second-order intermodulation component. A phase inversion element feeds an output current of the fundamental cancellation element to the transconductor pair of the double-balanced mixer circuit, to substantially remove the second-order intermodulation component from a differential output of the double-balanced mixer circuit.

摘要： A plurality of monitoring devices are arranged at different heights and steps, and infrared reflective assemblies of the monitoring device are set at different heights to collect infrared spectral data of chemical constituents of the air mass that are being diffused in airspace of different heights. The pollution factors contained in the air mass and the pollution level of each factor are learned by using IR spectrum for qualitative and quantitative analysis on the pollution factor, therefore realizing continuous monitoring in a certain area. Artificial duty is not required while 24-hour continuous intelligent monitoring can be achieved. Besides, meteorological data are collected in combination with the meteorological data collected by the meteorological information acquisition module at different heights and calculation is made based on the air diffusion model of various pollution factors to finally determine the position of air pollution source.

摘要： Methods, apparatuses, and systems are presented for switching between channels of encoded media data involving receiving encoded media data including reference frames and dependent frames for a plurality of channels, wherein each dependent frame refers to at least one reference frame. Frames associated with a first channel from the plurality of channels are decoded to generate a decoded signal for the first channel. While decoding frames associated with the first channel, data corresponding to at least one reference frame associated with a second channel from the plurality of channels are stored. In response to a control signal for switching from the first to the second channel, at least one dependent frame associated with the second channel is decoded by utilizing the stored data corresponding to the at least one reference frame associated with the second channel, to generate a decoded signal for the second channel.
