Personal microcomputers interfaced with analog-digital converters are capable of analyzing almost any biological signal, yet are limited in their ability to directly measure a signal's period/frequency. We describe a short program which measures the interval between periodic events up to 3.5 Hz. In addition, an expanded program which calculates the frequency distribution, distribution statistics, and cross regressions of cardiac interval and blood pressure is described.
