ECG HIGH PASS FILTER
First Claim
1. An electrocardiogram high pass filter, comprising:
- a baseline low pass filter including a finite impulse response low pass filter and an infinite impulse response low pass filter cooperatively structurally configured and operatively connected for low pass filtering a baseline unfiltered electrocardiogram signal (ECGbu) to output a filtered baseline signal (BSEf);
a signal delay operable for time delaying the baseline unfiltered electrocardiogram signal (ECGbu) to output a delayed baseline unfiltered electrocardiogram signal (ECGdbu); and
a signal extractor operably connected to the baseline low pass filter and the signal delay for extracting the filtered baseline signal (BSEf) from the delayed baseline unfiltered electrocardiogram signal (ECGdbu) to output a baseline filtered electrocardiogram signal (ECGbf).

Abstract
An electrocardiogram high pass filter (25) employs a baseline low pass filter (40), a signal delay (43) and a signal extractor (44). In operations, baseline low pass filter (40) includes a finite impulse response low pass filter (41) and an infinite impulse response low pass filter (42) cooperatively low pass filtering a baseline unfiltered electrocardiogram signal (ECGbu) to output a filtered baseline signal (BSef). Signal delay (43) time delays the baseline unfiltered electrocardiogram signal (ECGbu) to output a delayed baseline unfiltered electrocardiogram signal (ECGdbu), and signal extractor (44) extracts the filtered baseline signal (BSef) from the delayed baseline unfiltered electrocardiogram signal (ECGdbu) to output a baseline filtered electrocardiogram signal (ECGbf).
