尽管前置放大电路具有较高的共模干扰抑制能力,有些工频干扰是以差模形式进入放大器的;还由于包含电极在内的输入回路的不稳定等因素,解决的方法是用电平迁移和50Hz陷波器共同作用将工频干扰滤掉。
工频干扰信号中除了50Hz基波频率分量外,还有较多的100Hz、150Hz等谐波频率分量,这些频率分量经50Hz陷波后仍然存留于心电信号中。我们采用低通滤波器,最后通过主放大电路将电平放大到合适的幅度以便进行下一步的处理工作。

Though placed the big electric circuit to have the higher total mold interference to repress the ability before, some works interference entered the enlarger with the bad mold form of;Return because of including the electrode at inside of unsteady etc. factor of the importation back track, the method for solve is to use to give or get an electric shock the even migration and 50 Hzses to sink a machine common the function drop the work interference .
In the work interference signal in addition to the a frequency of 50 Hz weight, still have the a frequency weights, such as more 100 Hzs and 150 Hz...etc., these frequencies weight after 50 Hzs sink the wave still save to stay in the heart telecommunication number.We adopt a filter, enlarge through a lord the electric circuit and will give or get an electric shock to place levelly finally big arrive the fit range in order to carry on the processing work of the next move.

Although lead enlarged circuit interference with the higher total national capacity to contain some form of the frequency jamming is worse modules into amplifier; Also included electrode, because the instability of circuit elements solution is electricity ping wave devices common ground movement and the role of 50Hz frequency interference filter will work. In addition to the 50Hz frequency interference signals Mouttalos frequency weight, there are more 100Hz, 150Hz frequency harmonics, weight, the weight of these frequency 50Hz wave still remain trapped in the heart electrical signal. We use low-filter, and finally through the circuit will call ping enlarged enlarged to the extent appropriate for the next processing.

ok.
