A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Frequency is defined as the number of events of a particular sort occurring in a set period of time. Frequency counters usually measure the number of oscillations or pulses per second in a repetitive electronic signal. Such an instrument is sometimes referred to as a cymometer, particularly one of Chinese manufacture.

Famous quotes containing the words frequency and/or counter:
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
“The individual protests against the world, but he doesn’t get beyond protest, he is just a single protester. When he wants to be more than that, he has to counter power with power, he has to oppose the system with another system.”
—Friedrich Dürrenmatt (1921–1990)
