frekvenssihypyllä
Frekvenssihypyllä, often translated as frequency hopping, is a method of transmitting radio signals by rapidly switching a carrier frequency among many distinct frequencies over a short, determined sequence. This sequence is known to both the transmitter and the receiver. The purpose of frequency hopping is to improve the security of communication and to reduce interference.
By rapidly changing frequencies, a frequency-hopping signal is difficult to intercept or jam. An eavesdropper would
Frequency hopping is also used to mitigate interference in crowded radio spectrums. If a particular frequency
The hopping sequence is typically generated by a pseudo-random number generator, making it appear random to
