ABSTRACT:
A digital device for measuring single and multiple impact impulses comprises a unit for measuring the peak value of impact pulses, whose first input is connected to a unit for successive separation of impact pulse time intervals and a pause, whose first and second outputs are connected to the first and second inputs of a unit for separation of the first pulse and a group of further pulses from a train of high-frequency pulses filling the pause, whose third input is connected to the first output of the measuring unit. The second and third outputs of the measuring unit are connected to the first and second inputs of a unit for readout of information on single and multiple impact pulses, whose third input is connected to the first output of the unit for separation of the first pulse and to the second input of the measuring unit. The second output and the fourth input of the unit for separation of the first pulse are respectively connected to the input and the first output of a unit for setting operational modes for measuring single and multiple impact pulses, whose second output is connected to the fourth input of the unit for information readout, which ensures high-speed operation and accurate measurements.
