General Description
The ST158 Heart Pulse Detector is a single chip differential - sensing electrocardiogram heart pulse detection system. The preamplifier is built as a differential 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 signal 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.
