   Radio frequency ( RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies, and also ...

   Das Frequenzspektrum beschreibt, mit welcher Wichtung (d. h. Stärke) die zu der jeweiligen Frequenz zugehörige Aufbaufunktion in das Gesamtsignal eingeht. Zur rechnerischen Darstellung der Signalsynthese werden die Formeln zur Fourier-Rücktransformation dargestellt. Dazu ist es erforderlich zu unterscheiden, welche Art von Signal vorliegt.

   In the case of electrical current, frequency is the number of times a sine wave repeats, or completes, a positive-to-negative cycle. The more cycles that occur per second, the higher the frequency. Example: If an alternating current is said to have a frequency of 3 Hz (see diagram below), that indicates its waveform repeats 3 times in 1 second.

   The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz ). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission of radio ...

   7. Juni 2022 · To calculate the relative frequencies, divide each frequency by the sample size. The sample size is the sum of the frequencies. Example: Relative frequency distribution. From this table, the gardener can make observations, such as that 19% of the bird feeder visits were from chickadees and 25% were from finches.
