carrier current frequency
1Carrier current — is a method of low power AM broadcasting that does not require a broadcast license in the United States, but is allowed on the campus of any school, so long as the normal FCC Part 15 Rules are adhered to when measured at the edge of the campus.… …
2Frequency comb — A frequency comb is the graphic representation of the spectrum of a mode locked laser. An octave spanning comb can be used for mapping radio frequencies into the optical frequency range or it can be used to steer a piezoelectric mirror within a… …
3Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… …
