What unit is frequency measured in?

Frequency is measured in Hertz (Hz), which defines the number of cycles per second for a periodic wave or signal. When we refer to frequency in the context of telecommunications and electronics, it typically signifies how many times a signal oscillates or repeats itself within one second. For example, a frequency of 60 Hz indicates that a signal completes 60 cycles every second. This measurement is fundamental in various applications including radio communications, audio signals, and electromagnetic wave propagation, making it essential in understanding how electronic devices operate and communicate.

Other options do not represent measures of frequency: cyclic units are not a standard measurement for frequency; decibels are used to express ratios of power or intensity, often in acoustics and electronics; and watts measure electrical power, not the frequency of oscillations. Understanding these distinct units helps clarify the role of frequency in communications and its importance in system design.
