ABSTRACT:
Analog or digital systems and methods generate a composite signal derived from a biological event in a time-sequential fashion. The systems and methods input a first set of signals derived from a biological event using a first group of sensors during a first time interval. The systems and methods input a second set of signals derived from the biological event during a second time interval sequentially after the first time interval using a second group of sensors. The second group of sensors has at least one common sensor that is part of the first group and other sensors that are not part of the first group. The systems and methods time align the first and second sets of signals using the signals sensed by the at least one common sensor, thereby generating the composite signal. The systems and methods time align by shifting the first and second sets of signals either with or without computing a time difference between them.
