中频

The key point of this thesis is to provide an alternative for the mass production of IF band-pass filter design.

全文重点乃是试图为中频滤波器的设计方法扩展更大的思考空间。

It usually achieved in the baseband and IF band to achieve.

它的实现通常在基带和中频频段上实现。

Better yet, over the critical midrange between 250 Hz and 2.5 kHz the variation was only +/-2 dB, which would be a remarkable achievement for even a considerably more expensive speaker.

在250到2.5kHZ 的中频测试中，它的偏离度只有＋/－2DB ，通常只有价格极为昂贵的天价音箱才具有这类技术优势。。。。

Double channel bandpass sampling method for wide band IF signal is presented to settle the problem of blind zone,which exchanges one more sampling channel for simplification of clock circuit and band pass filter.As a practical reconnaissance receiver, real-time processing performance must be considered.Digital channelizing method lays the base of parallel processing by multi DSP chips and discarding of the redundant data resulting from double channel bandpass sampling.

针对带通采样存在着频率覆盖盲区的问题，提出了宽带中频信号双通道带通采样的方法，通过增加一个采样通道既解决了传统处理盲区方法中设计复杂采样时钟电路、高矩形系数滤波器的困难，还缓解了后续DSP处理压力。
