Abstract: A information transmission circuit for transforming periodic input signals having a duration indicative of the information to be transmitted into a relatively continuous output signal, the amplitude of which is cumulatively changed in accordance with the duration of the periodic signal. The input signals are applied to a first energy storage means or capacitor, and a first gate comprising a diode clamping circuit is connected across the capacitor. A second energy storage means or capacitor is included for developing the output signal, and a second gate comprising a diode clamping circuit is connected from this capacitor to the first gate and first capacitor. In accordance with an additional aspect of the invention, the second gate includes semiconductor switching means comprising first and second transistors for connecting an auxiliary voltage source to the second capacitor which transistors are controlled by the voltage on the first capacitor.
