Abstract:
1. A time interval measurement device comprising: input of a pulse signal connected to a serial chain comprised of a filter exciter connected through a surface acoustic wave filter and an amplifier to an analog input of a sampler, an output of said sampler being connected to an analog input of an analog-to-digital converter, an output of said converter being connected to a digital input of a sample register, an output of said sample register being connected to a first input of a computer, while said input of said pulse signal is further connected through a voltage comparator to a trigger input of a control circuit, a first write output of said control circuit being connected to a write input of said sample register, and a second write output connected to a write input of a register of sample numbers, whose output connects to a second input of the computer, and a digital input of a register of sample numbers connected to an output of the sample counter, the input of the sample counter together with the trigger input of the analog-to-digital converter, the sampling input of the sampler, and a clock input of the control circuit connect to an output of a reference clock signal source, and an output of the computer being an output of measured time intervals.
