Abstract :
Switched capacitor filters are integrated into a hand-held electrocardiograph. Analysis of repetitive signals from human subjects is facilitated by an exceptionally large rolloff (100 dB/dec) at low frequencies (20 Hz). Sensitivity to harmonics is easily accomplished by changing a single resistor setting. Signal analysis of this cleanliness and selectivity has, up to now, only been possible on very, very large machines
