notch amplifier

基本解释

ECG signal sampling module design, including preamplifier, high pass filter, 50Hz notch filter, electrical level rising and primary amplifier, ADC and FPGA.
心电采集模块的设计，包括心电前置放大、高通滤波、工频陷波、电平抬升和主放大、A/D转换和FPGA采样电路。
During signal processing, choosing low noise, high-precision, low-power amplifier AD620 as a pre-amplifier, and high-and low-pass filter and the frequency notch filter removal of interfering signals.
在信号处理中选用具有低噪声、高精度、低功耗放大器AD620作为前置放大器，并以高、低通滤波器和工频陷波器清除干扰信号。
