  • Digitally controlled amplitude regulating device for electrocardiographic signals
    Patent number: 4325384
    Abstract: A signal processing device composed of: a signal input for receiving an electrocardiographic signal containing a succession of QRS complexes; a signal output; a digitally operating unit having a transmission factor which is variable in discrete steps and connected between the signal input and output for supplying to the signal output a signal containing representations of the QRS complexes contained in the signal received by the signal input, with the relation between the amplitude of the signal at the signal output and the amplitude of the corresponding portions of the signal received by the signal input being proportional to the existing transmission factor of the digitally operating unit; and a transmission factor control unit connected to monitor the signal at the signal output for increasing the transmission factor of the digitally operating unit by one step in response to each appearance at the signal output of a QRS complex representation having a peak value between selected first and second threshold
