. The Bell System technical journal . ated earlier, the integrator generates a voltage ramp in responseto a voltage step. This step is applied through a transistor switch whichis actuated by a square wave generator capable of driving the transistorwell into current saturation. Such a switch is required because theequivalent generator impedance of the applied step voltage must be verysmall. A suitable circuit arrangement is shown in Fig. 15. For the par-ticular application under discussion the sw
