✦ Synopsis

A hardware trigger has heen constructed to aid in the alignment of SLICcessive waveforms in real-time averaging of electrocardiographic signals on a general purpose digital computer. The device minimizes demands on central processor time and core storage while providing accurate time alignment to within plus or minus one sample for analog-to-digital conversion rates in excess of 500 samples per second. The performance of the hardware trigger 15 analyzed in detail for various types of electrocardiographic signals. The xtahility of the electrocardiographic signal is also examined.
