[Broad-band analogue-to-digital converter of electrocardiograms].
The use of a broad-band analogue-to-digital converter (ADC) with a reading rate of up to several kilohertz and with a subsequent digital filtration and decimation provides for obtaining the amplitude-and-frequency characteristics with the parameters, which are virtually unachievable for the ordinary analogue scheme technologies or digital filters inbuilt into the digital-filter integral ADC. Multi-digit ADC and digital signal processors (DSP) are used for the purpose. Additionally, with DSP it is possible to process algorithms of the broad-band ECG, like isolation of the impulse of the cardiac pacemaker.
