megacycle
/'megə,saikl/
Definition
- Noun:
- A unit of frequency equal to one million cycles per second: A "megacycle" is a measurement of frequency, specifically representing one million complete cycles of a wave occurring in one second. This term is an older name for the unit now more commonly called a megahertz (MHz).
Usage Examples
- Noun:
- The radio station broadcasts at a frequency of 1.2 megacycles.
- Early technical specifications for this device listed its operating frequency in megacycles per second.
Advanced Usage
- The term "megacycle" is considered somewhat dated in modern technical and scientific contexts. It has been largely replaced by the SI unit "megahertz" (MHz), where 1 megacycle = 1 megahertz.
- The old manual refers to a 5-megacycle signal, which we would now call a 5-MHz signal.
Variants and Related Words
- Megahertz (MHz) (n): The modern, standard unit of frequency equal to one million hertz (cycles per second). This is the preferred term.
- Modern processors have clock speeds measured in gigahertz (GHz), which are thousands of megahertz.
- Kilocycle (n): An older term for a unit of frequency equal to one thousand cycles per second, now called a kilohertz (kHz).
Synonyms
- Megahertz (MHz): The direct modern equivalent and synonym for "megacycle."
Noun
-
one million periods per second
