выполн тьс условие К К am , откуда N NZ, т. е. при считывании числа Л, записанного за предшествующее врем р , в счетчике остаетс остаток (не происходит полного считыва«и ).the condition K K am, whence N NZ, is fulfilled, i.e., when reading the number L written at the previous time p, the remainder remains in the counter (full reading of the "u" does not occur.
Точность контрол легко повыщаетс при увеличении частоты FQ калиброванных импульсов и увеличении емкости счетчика.The accuracy of the control is easily increased by increasing the frequency FQ of the calibrated pulses and increasing the capacitance of the counter.
Предмет изобретени Subject invention
Способ контрол импульсного коэффициента импульсов набора номера в автоматической телефонии, заключающийс в формировании пр моугольных импульсов длительионостью размыкани tp и замыкани /з и последующем подсчете импульсов калиброванной частоты FO за врем tp , отличающийс тем, что, с целью повышени точности контрол , за врем )з подсчитанные импульсы считываютс импульсами двух частот FI и fg, соответствующих верхнему и нижнему значени м импульсного коэффициента, а по наличию остатка при считывании с частотой Р и отсутствию остатка при считывании с частотой F определ ют нахождение импульсного коэффициента в заданных пределах.The method of controlling the pulse coefficient of dialing pulses in automatic telephony, which consists in the formation of rectangular pulses with a trip time tp and closure / s and subsequent counting of calibrated frequency FO pulses during time tp, characterized in that the counted pulses are read by the pulses of the two frequencies FI and fg, corresponding to the upper and lower values of the pulse coefficient, and by the presence of the residue when reading with the frequency P and the absence of the remainder and when reading at a frequency F, the finding of the impulse coefficient within the specified limits is determined.
