Los sistemas FHSS pueden ser de salto lento en frecuencia (Slow FHSS) o salto rápido en frecuencia (Fast FHSS) [3]. Webb5 dec. 2024 · We have a slow-hopped signal in the FH system if the hopping is performed at the symbol rate. As a result, with slow-frequency hopping, the MFSK signal's symbol rate Rs is an integer multiple of the hop rate Rh, implying that various symbols are transmitted per each frequency hop.

Webb9 nov. 2013 · Screwdriver! The actual RF chips are different. FASST uses the ML2724 (+their own chip for the DSSS modulation), where as S-FHSS uses the CC2500. The CC2500 is the same chip that is used in FrSky/Hitec/Graupner and other systems. FASST is both DSSS modulation (like DSM2) and FHSS (frequency hopping) - much like DSMX.
