MULTICHANNEL TIME INTERVAL METER Russian patent published in 2011 - IPC G04F10/04 

FIELD: physics.

SUBSTANCE: proposed meter comprises second memory, register and input generators each comprising front counter, slice counter, front and slice selector, first and second AND elements with their first inputs connected to front and slice counters, respectively, while their second inputs connected to count inputs of front and slice counters and to first and second outputs of front and slice selector, respectively, selector data input being connected to relevant inputs bus, while clock inputs is connected to clock pulse bus and to write inputs of first and second memories with their resolution inputs connected to switch output and count input of first counter with its outputs connected to group of address inputs of second memory and data inputs of registers with its clock input connected to reset input of first counter and reference pulse bus. Outputs of first and second AND elements of each input generator are connected to appropriate data inputs of switch with its address inputs connected to second address inputs of first and second memories with their control inputs connected to non-inverting and inverting outputs of trigger while first addresses are combined. Note here that first and second memory represent two-port RAM while trigger represent count trigger with its input making count input.

EFFECT: increased measurement interval without complicating circuit configuration.
