Abstract: An electronic chronometry system for measuring a time T between a starting instant and a stopping instant which utilizes a ramp vernier having time expansion in order to provide fine counting between a starting instant and a beginning of a clock signal and for measuring a second time between the stopping instant and a second beginning of a clock signal. The device also utilizes a rough counting device to count the number of clock periods between the beginnings of the two clock signals. The system further utilizes a compensation circuitry for determining the nonlinearity in the ramp signal in order to determine the corrective term which must be applied. The corrective term is determined during a calibration cycle as a function of the measured parameters including the first and second time periods which are measured.

Abstract: A system for digitizing transient signals comprises a plurality of high-speed sampling gates connected in parallel to a common input terminal, these gates working in interleaved relationship into respective charge-transfer devices each including a multiplicity of storage cells which are successively loaded in a first operational phase with analog samples delivered by the corresponding gate. After having been fully loaded, the several transfer devices are read out cell by cell in a second operational phase via a multiplexer into an analog/digital converter at a rate which is substantially lower than the sampling rate.

Abstract: Multiplexers and demultiplexers including sampling gates in the form of diode bridges are disclosed. Plural-input gates, each formed from two or more diode bridges with two adjoining arms in common, are utilized in a multiplexer designed to synthesize a multi-level output train from a number of binary input trains exceeding the number of gates.
