Claims (2)

1. The method of forming time stamps, including the formation of n (n = 1, 2, 3, ...) sequences of pulses with a period τ ₁ (i = 1, 2, ... n), and the ratio τ ₁ / τ _{(i + 1)} = k, where k is an integer, the formation of each subsequent time stamp М _j (j = 1, 2, ... m, m is the number of time stamps) after a time interval

, where p _ji = 0, 1, 2, ... (k-1), characterized in that they form a digital signal C by sequentially adding p _ji pulses of those sequences that define the time interval T _j , and in the time interval T _j sequentially summing first, p _j1 pulses with a maximum repetition period of τ ₁ , then p _j2 pulses with a shorter repetition period of τ ₂ and so on, until p _jn pulses with the shortest repetition period τ _{n are} added, and timestamps M _j are formed at time t _r (r = 1, 2, ... m) when digital signal C is equal to

. 2. A time-stamping device comprising a time interval generator, first and second counters, a digital comparator, programmable memory and a first decoder, the output of which is connected to the output bus of the device, and the output bus of the second counter is connected to the control bus of the first decoder and to the address bus programmable storage device, the output bus of which is connected to the bus A of the digital comparator, the bus B of which is connected to the output bus of the first counter, and the output A = B of the digital the comparator is connected to the counting input of the second counter, characterized in that a second decoder and multiplexer are additionally introduced into it, the signal inputs of which are connected to the corresponding outputs of the time interval shaper, the multiplexer output is connected to the counting input of the first counter, the multiplexer control bus is connected to the output bus of the second decoder whose control bus is connected to the output bus of the second counter.
