1.	The waveform used in a coherent BFSK modulation scheme are as followss0(t)=cos(2πf1t) 0≤t≤Tbs1(t)=cos(2πf2t) 0≤t≤TbThe scheme uses s0(t) to transmit logic '0' and s1(t) to transmit logic 1. The bit rate of the system is Rb=50 kbps. If it has to be ensured that the consecutive bits have a phase continuation and they are also orthogonal, then the minimum value of \|f2−f1\| is equal to _________ kHz.25
Answer» The waveform used in a coherent BFSK modulation scheme are as follows $s_{0} (t) = cos (2 π f_{1} t) 0 \leq t \leq T_{b} s_{1} (t) = cos (2 π f_{2} t) 0 \leq t \leq T_{b}$ The scheme uses $s_{0} (t)$ to transmit logic '0' and $s_{1} (t)$ to transmit logic 1. The bit rate of the system is $R_{b} = 50 k b p s .$ If it has to be ensured that the consecutive bits have a phase continuation and they are also orthogonal, then the minimum value of $\| f_{2} - f_{1} \|$ is equal to _________ kHz. 25
