GHz(gigahertz)

Gigahertz (GHz) is a unit of frequency used to measure electromagnetic waves or signals, particularly in the field of radio and telecommunications. It represents one billion cycles per second or one billion Hertz (Hz). In other words, a frequency of 1 GHz means there are 1,000,000,000 oscillations or cycles of a signal occurring in one second. GHz is often used to denote the frequencies of various wireless communication systems such as radio, television broadcasting, mobile phones, Wi-Fi networks, and satellite communication systems, as well as the clock speeds of computer processors.

µHz(microhertz)

In the field of frequency, µHz (microhertz) is a unit of measurement that represents a frequency of one millionth (1/1,000,000) of a hertz. Frequency is the number of occurrences of a repeating event per unit of time, typically represented using the unit "hertz" (Hz). One hertz is equal to one cycle or oscillation per second. A microhertz (µHz), therefore, represents an extremely low frequency where there is one cycle or oscillation per million seconds (1,000,000 seconds or roughly 11.6 days). This unit is used to describe extremely low-frequency signals or processes, such as certain astronomical or geophysical phenomena.
