Abstract
An electrocardiographic amplifier having an integrator in the feedback loop between the amplifier's input and output whose time constant is varied by the duty cycle of a series switch to vary the low frequency 3 dB roll-off point as a function of the detected low frequency noise in the amplifier output signal. A capacitor is switched in parallel with the inverting feedback resistor to lower the high frequency 3 dB roll-off point in response to detected high frequency noise.
