接触式心率测量IC, 测量精确, 噪音滤波, 心率脉冲输出.The ST158 Heart Pulse Detector is a single chip differential-sensing electroncardiogram heart pulse detection system. The preamplifier is built as a differentail input instrument amplifier for preprocessing heart pulse signal from input sensors. With built-in A/D converter, the analog heart pulse signal is sampled and digitized as digital signal for further processing by digital means. The internal digital processor tracks input digital signals and extracts out digital heart pulse signal by suppressing down noise signals which came with heart pulse sigale from input sensors. There are two output formats of heart pulse signal. One is traditional single digital pulse form. The other is digital wave form of heart pulse signal.ST158心脏脉搏探测器是一种单芯片差分感应electroncardiogram心脏脉搏检测系统。前置放大器是建成一个微分方程输入预处理的心脏脉搏传感器的输入信号的仪表放大器。由于内置的A / D转换器，模拟心脏脉冲信号进行采样和数字信号进行进一步处理数字化的数字方法。内部数字输入的数字信号处理器跟踪并提取出通过抑制了噪声信号，患有心脏病的输入传感器脉冲信号到数字心脏脉冲信号。心脏有两个脉冲信号输出格式。一种是传统的单数字脉冲形式。另一种是心的数字脉冲信号波形。
