frequency

Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period—the time interval between beats—is half a second (that is, 60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio (sound) signals, radio waves, and light.

    How to undo remote frequency change

    I bought a 32in Hisense smart tv but the remote was also setting off my pedestal fan. I read another thread telling me to go to tv name, type 2018 then choose another code. I chose 2.

    Most computers users still measure memory frequency in megahertz, when they have been measuring CPU and GPU frequency ion gigahertz for at least two decades, now, and I wonder why that is. Why do people still bother to say that memory operates at 5,000 or 6,000 megahertz, when it would maintain...
