摘要
In providing digital filters for remote control receivers, in particular, for audio-frequency centralized ripple control receivers in an economic manner, it is advantageous to be able to use a processor unit with as low a bit number as possible (for example, an 8-bit microcomputer). In a conventional design of a filter according to the prior art, the dynamic range which is provided with an 8-bit processor element is insufficient in ensuring a perfect operation of the filter when a quality factor Q of about 30 is needed for the intended purpose of use and, on the other hand, when the dynamic range of the wanted signal which is given in practice is taken into consideration. A solution is indicated which overcomes these difficulties, which particularly involves the selected arrangement of zeros in the pass-band of the filter.
