In a normal EEG the frequencies are predominately within the range of alpha and beta rhythms at the rate of 8 to 30 hertz (cycles per second). During sleep the brain cells generate higher voltage electrical waves, but the rhythm is slowed down to 2 or 3 hertz, sometimes with short âsleepâ spindles of about 15 hertz.
In English, hertz is also used as the plural form. As an SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz, 10 3 Hz), MHz (megahertz, 10 6 Hz), GHz (gigahertz, 10 9 Hz) and THz (terahertz, 10 12 Hz).hereas 1 Hz is 1 cycle per second, 1 Bq is 1 aperiodic radionuclide event per second. Even though angular velocity, angular frequency and the unit hertz all have the dimension 1/s, angular velocity and angular frequency are not expressed in hertz, but rather in an appropriate angular unit such as radians per second.
