The invention provides a filter used for a digital baseband receiving machine. The filter is used for carrying out analogue to digital conversion (A/D) for the radio-frequency signals received by the digital baseband receiving machine and the digital decimating filtering of the output signal of the digital lower frequency conversion. The filter is an Infinite Impulse Response (IIR) filter. The IIR filter is used to replacing the finite impulse response filter and be taken as the filter of the digital baseband receiving machine so as to reduce the order of the filter, thus reducing the operation quantity and the requirement to the hardware resource of the receiving machine; therefore, the chip area of the baseband receiving machine is saved and the system power dissipation of the baseband receiving machine is reduced. Furthermore, the IIR filter designed by the invention has the advantages of simple structure and stable performance.

Принадлежит:

The invented releaser is available for use for releasing the pure beauveria spore powder. As the said powder is used as usual, the filler must be added, and the mixture is released by airplane of atomized spreaying machine. Since the transportation of filler is rather difficult, and the stirring operation hardly makes the mixture even, so the infection effect is poor. In order to solve the problem mentioned above, the invented releaser is presented. Its advantages are: easy to get raw material, simple in production, no filler added, direct releasing the powder, low cost, convenient in operation, practical and reliable, and saving of labour and money.
