Why do OOK (on-off key) transmissions have bandwidth? - Quora
WebOn–off keying (OOK) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a binary zero. Some more sophisticated … Web1 de set. de 2016 · Radio Observation. Alexandru Csete’s gqrx software defined radio comes in as a handy spectrum analyzer when looking for exact frequencies. It’s mainly based on the GNU radio project and supports all well-known platforms (Ettus USRPs, BladeRF, HackRF, RTL chipset et. al). flagler county maps
