Abstract: An integrator for an electrical signal is provided with means for changing integrating rates without attenuating the input signal or utilizing a potentiometer to give different degrees of attenuation for this purpose. Instead of attenuating the input signal with varying degrees of attenuation, means are provided to control the proportion of time that the full input signal is applied to the integrator. Adjustable, pulse-length controlled electronic switches are employed for alternately changing the gain of the integrator, in order to control the length of time that the signal is applied to the integrator.
