WebThe translation process does not reproduce the original binary sequence, but a bandlimited version of it. The original binary sequence can be regenerated with a detector. This requires information regarding the bit clock rate. If the bit rate is a sub-multiple of the carrier frequency then bit clock regeneration is simplified. WebA binary frequency shift keying system employs two signaling frequencies 1f and 2f. The lower frequency 1f is 1200 Hz and signaling rate is 500 Baud. Calculate 2f. ? For binary FSK baud=fb Fb=500Hz Consider the FN modulation index (h) of 1 in FSK Fm-fs/Fb =h=1 Fm-fs=fb Fs=f1=1200HZ Fm-1200Hz=500Hz Fm=1700Hz,f2=fm=1700Hz. 3. reading birds note cards
