hertz (Hz): a unit of frequency defined as one cycle per second 赫兹:定义为每秒一个周期的频率单位。 Examples: One hertz is very low frequency. The human ear hears sound in the 20 Hz to 10,000 Hz range. A wave’s frequency is measured in hertz. inductance: the ability of a material...
In technology and communications, hertz is commonly used to describe the frequency of signals. For example, the frequency of a computer processor is measured in gigahertz (GHz), which indicates how many billions of cycles the processor can complete in one second. Similarly, radio waves and wirele...
