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心臟脈搏探測器是一種單芯片差分感應electroncardiogram心臟脈搏檢測系統。前置放大器是建成一個微分方程輸入預處理的心臟脈搏傳感器的輸入信號的儀表放大器。由于內置的a / d轉換器，模擬心臟脈沖信號進行采樣和數字信號進行進一步處理數字化的數字方法。內部數字輸入的數字信號處理器跟蹤并提取出通過抑制了噪聲信號，患有心臟病的輸入傳感器脈沖信號到數字心臟脈沖信號。心臟有兩個脈沖信號輸出格式。一種是傳統的單數字脈沖形式。另一種是心的數字脈沖信號波形。
