    摘要: A method of packet transmission for a supervisor node in a mesh network with connectionless packet flooding transmission is disclosed. The method comprises requesting a neighbor list of a node of the mesh network, wherein the neighbor list indicates at least a neighbor node of the mesh network which is distributed in a coverage of the node, obtaining the neighbor list from every nodes of the mesh network, establishing a route table for every nodes of the mesh network according to the obtained neighbor lists, and establishing a transmission route from a source node to a destination node of the mesh network according to the route table when a request for transmitting a large amount of data to the destination node is received from the source node.

    摘要: A single-conversion integrated circuit TV tuner (100, 300) includes a first filter (103, 302) coupled to an RF signal input (RF), and a harmonic rejection mixer (105, 305) connected to a real output of the first filter (103, 302). The harmonic rejection mixer (105, 305) has complex output. The TV tuner (100, 300) further includes a polyphase filter (106, 306) having complex input connected to the complex output of the harmonic rejection mixer (105, 305). Only a real signal is passed from the first filter (103, 302) to the harmonic rejection mixer (105, 305).

    摘要: An integrated tuner (100) includes circuitry (105) to receive a television signal, a quadrature mixer (110) coupled to the output of the circuitry, a polyphase filter (120) coupled to the output of the quadrature mixer (110), a relaxation oscillator (140), and a digital calibration module (130). The relaxation oscillator (140) generates a clock having a period that is directly proportional to the on-chip RC time constant. The clock is fed into a counter (160) of the digital calibration module (130). The counter (160) is started and stopped at predefined time intervals by a finite state machine (170). The finite state machine (170) updates the calibration code based on a successive approximation algorithm according to the end count results received from the counter (160). The digital calibration module (130) outputs the updated calibration code to the polyphase filter (120) and to the relaxation oscillator (140).
