Изобретение относитс к вычислительной технике и может быть использовано при обработке информации, поступающей с датчиков технологических объектов.The invention relates to computing and can be used in the processing of information from the sensors of technological objects.
Известно устройство определени экстремума сигнала, которое наиболее близко по технической сущности к изобретению, содержащее блок сравнени , генераторы, триггеры,одновибраторы , логические элементы И и счетчики 1.A device for determining the extremum of a signal, which is the closest in technical essence to the invention, comprising a comparison unit, generators, triggers, single-oscillators, logic gates And counters 1, is known.
В этом устройстве измерение экстремума сигнала производитс последовательным суммированием приращений амплитуды входного с.игнала, определ емых за два цикла развертывающего преобразовани , к начальному значению сигнала, вычисленному в течении первого периода развертывающего преобразовани , а о наличии экстремума суд т по равенству нулю указанных приращений. Поскольку сами приращени входного сигнала вычисл ютс с погрешностью, котора в основном определ етс работой устройства сравнени и одновибраторов, т.о cy лмиpoвaниe их при измерении экстремума сигнбша приводит к накоп- .лёнию статической погрешности. Отыскание экстремума сигнала в известном устройстве происходит за два периода развертывакшего преобразовани , что-ограничивает сверху частотныйIn this device, the signal extremum is measured by successively summing the increments of the amplitude of the input signal, determined in two cycles of the sweep, to the initial value of the signal calculated during the first period of the sweep, and the presence of the extremum is judged to equal the zero increments. Since the increments of the input signal themselves are calculated with an error that is mainly determined by the operation of the comparator and single-shotrs, that is, cy- lining them while measuring the extremum of the signal leads to an accumulation of static error. The extremum of the signal in the known device is found in two periods of unwrapped conversion, which limits the frequency from above.
5 спектр анализируемого входного сигнала , т.е. увеличиваетс динамическа ошибка.5 spectrum of the analyzed input signal, i.e. dynamic error increases.
Цель изобретени заключаетс в повышении точности отыскани и из10 мерени экстремумов сигнала.The purpose of the invention is to improve the accuracy of finding and measuring signal extremes.
Достигаетс это тем, что в устройство дл обнаружени и измерени экстремумов сигнала, содержащее генератор тактовых импульсов, первыйThis is achieved by the fact that in a device for detecting and measuring extremes of a signal, comprising a clock pulse generator, the first
