A frequency counter is an electronic instrument , or component of one, that is used for measuring frequency. Frequency counters usually measure the number of cycles of oscillation, or pulses per second in a periodic electronic signal.
If the AC is being generated by an electromechanical alternator, the frequency will be directly proportional to the shaft speed of the machine, and frequency could be measured simply by measuring the speed of the shaft. If frequency needs to be measured at some distance from the alternator, though, other means of measurement will be necessary. One simple but crude method of frequency measurement in power systems utilizes the principle of mechanical resonance.

Frequency and Phase Measurement
By counting seconds, we can determine the date and the time-of-day. And by counting events or cycles per second, we can measure frequency. Time interval and.

A Time and Frequency Measurement Technique Based on Length Vernier Abstract: A simple length vernier approach has been developed which uses the high stability and high speed of signal transmission and the relation of time and space.
Electrical engineers consider the oscilloscope as one of the most important equipment in their lab. Since most of the signals are cyclical in nature or are repetitive at a specified period time, knowing the frequency when signals repeat is of utmost importance. Signals can be used through a dedicated probe or through a less sophisticated cable.

One simple but crude method of frequency measurement in power systems utilizes the principle of mechanical resonance. Every physical object possessing the property of elasticity springiness has an inherent frequency at which it will prefer to vibrate. The tuning fork is a great example of this: strike it once and it will continue to vibrate at a tone specific to its length.
Сьюзан, я хочу кое о чем тебя спросить.
Арест никак не вписывался в его планы. Росио подошла еще ближе и изучающе смотрела на. - Хорошо, - вздохнул он, всем своим видом признавая поражение. Его испанский тут же потерял нарочитый акцент. - Я не из севильской полиции. Меня прислала сюда американская правительственная организация, с тем чтобы я нашел кольцо.
Лейтенант следил за его взглядом. - Ужасное уродство, правда. Но не искалеченная рука привлекла внимание Беккера. Он увидел кое-что другое. И повернулся к офицеру.
Позвоните в банк данных! - приказала Сьюзан. - Предупредите их о вирусе. Вы заместитель директора АНБ и обязаны победить.
