AFSK transcever for Silicon labs Si446x An AFSK signal is an FSK signal whose DR changes with the two audio tones’ frequency. As an example take the Bell 202 modulation format where one audio frequency is 1200 Hz while the other is 2200 Hz. From the receiver’s perspective these signals translate to 2400 bps and 4400 bps DR streams, respectively. The reason the DR is twice as much as the audio tone frequency is that a full c... 5 工程, 电子, 微控制器, 电機工程 Feb 22, 2018 Feb 22, 20184天 11时 ¥1901
