COMPARATOR NETWORK OF AN APPARATUS FOR DETECTING AND TRANSMISSION OF A HEART RATE PERIOD

COMPARATOR NETWORK OF AN APPARATUS FOR DETECTING AND TRANSMISSION OF A HEART RATE PERIOD

The comparator is formed by an operational amplifier (3), with the compared ECG signal connected to the non-inverting input (31) and to its inverting input (32), by means of controlled switch (34), the source (36) of saw tooth voltage, which forms a dynamic comparative threshold, and which is always...

description The comparator is formed by an operational amplifier (3), with the compared ECG signal connected to the non-inverting input (31) and to its inverting input (32), by means of controlled switch (34), the source (36) of saw tooth voltage, which forms a dynamic comparative threshold, and which is always at an interval between the comparative or points on the rising part of the ECG waveform (4) and top of the corresponding period restored so that, at the time moment corresponding to the given comparison, the source (36) is disconnected from the inverting input (32) of the operational amplifier (30) and this input is switched to zero potential, where it remains until the moment when the downward part of the ECG signal (4) goes past zero. Interval between the two following passages of the ECG signal pass zero is the defined pulse period of the pertinent section of the ECG signal.
