A demodulator, suitable for use in a communication system and in a modem, has a block polyphase circuit with circuit blocks for different signal processing functions, particularly filtering, delay, and frequency conversion. The circuit blocks are arranged for parallel processing of different portions of an input sequence of signals. Signals of the input sequence to be filtered are divided among the blocks by a demultiplexer for processing at a clock frequency lower than a clock frequency of the input signal sequence. Signals outputted by groups of the circuit blocks are summed to produce an output signal of the group. Frequency and timing reference signals, as well as fractional delay interpolation, are produced also by parallel-channel circuitry. Output signals of all of the groups are multiplexed to provide an output signal sequence such that the repetition frequency of the outputted signals may be higher, lower, or equal to that of the input signal sequence. This enables use of programmable circuitry operative at clock rates lower than rates required to process directly the input signal sequence.

Magnetic resonance imaging uses a pulse sequence formed to include a pre-pulse, an RF excitation pulse, an encoding gradient pulse, and a reading gradient pulse. The encoding gradient pulse has an encoding amount determined to allow a data acquisition position in a k-space to be directed outward from a center of the k-space. A train of pulses including the RF excitation pulse, the encoding gradient pulse, and the reading gradient pulse is repeated to allow the number of times of data acquisition in the k-space to become larger as approaching to a central region of the k-space. The pre-pulse is formed to be reduced in an application rate to the RF excitation pulse as approaching to an outward position in the k-space. By way of example, this pulse sequence is used for contrast enhanced MRA carried out under a dynamic scan.

A block polyphase filter is constructed of a set of filter blocks having different filter functions, and being arranged for parallel processing of portions of an input sequence of signals. Signals of the input sequence are divided among the blocks by a demultiplexer for processing at a clock frequency lower than a clock frequency of the input signal sequence. The filter blocks are arranged in groups, wherein output signals of the blocks in any one group are summed to produce an output signal of the filtered group. Output signals of all of the filter groups are multiplexed to provide an output signal sequence wherein the repetition frequency of the signals may be higher, lower, or equal to the repetition frequency of the input signal sequence depending upon the ratio of the number of filter groups to the number of filter blocks in the set of filter blocks.

The invention relates to a weeding composition, and especially relates to the weeding composition comprising propyrisulfuron and bensulfuron methyl, use of the weeding composition, and a corresponding method of weed control. Active ingredients of the weeding composition comprise the propyrisulfuron and the bensulfuron methyl, wherein a weight ratio of the propyrisulfuron to the bensulfuron methyl is 200:1 to 1:200. The weeding composition is used for control of gramineae weeds, broadleaf weeds and cyperaceae weeds in crop growth environment. According to the invention, the weeding composition is prepared by complex formulation of herbicides comprising the propyrisulfuron and the bensulfuron methyl. Because the propyrisulfuron has prevention and control capability to weeds that show resistance to known sulfonylurea herbicides, and the weeding composition is prepared by binary complex formulation of the two herbicides, the weeding composition has an enhanced effect. Compared with single use of one herbicide, the prevention and control effect on the weeds is significantly enhanced and a weed killing spectrum is enlarged.

The invention relates to a herbicidal composition, and particularly relates to a herbicidal composition comprising propyrisulfuron and pyrazosulfuron, and an application thereof and a corresponding weed control method. The herbicidal composition comprises active components of propyrisulfuron and pyrazosulfuron, wherein a weight ratio of propyrisulfuron to pyrazosulfuron is 200 : 1-1 : 200. The herbicidal composition is used for controlling grassy weeds, broad leaf weeds and cyperaceae weeds in the rice fields in crop growth environment. Compared with an individually used herbicide, the herbicidal composition compounded by the propyrisulfuron and pyrazosulfuron enlarges herbicidal spectrum and significantly enhances a weed control effect because propyrisulfuron has a control capability for weeds having resistance to known sulfonylurea herbicides and binary compound of the two herbicides allows the herbicidal composition to have an enhanced effect.
