Efficient Multirate EMQF Digital Filters

摘要

The operating rate of digital programmable chips can be significantly larger than the required processing rate for digital signal processing applications. The efficiency of digital filter implemented on the programmable hardware, such as field programmable gate array (FPGA) chips, can be very low, because in the most of the available operating time the implemented digital filter is not used. The efficiency of the implementation of digital filter on a programmable or dedicated hardware can be considerable improved when using the same hardware more than ones during the sampling period.
