Coherent orthogonal binary FSK modulation is used to transmit two equiprobable symbol waveforms s 1 (t) = αcos2πf 1 t & s 2 (t) = αcos2πf 2 t 1 where α = 4 mV. Assume an AWGN channel with two-sided noise power spectral density $$\frac{{{N_0}}}{2} = 0.5 \times {10^{ - 12}}W/Hz.$$ Using an optimal receiver and the relation $$Q\left( v \right) = \frac{1}{{\sqrt {2\pi } }}\int\limits_v^\infty {{\theta ^{\frac{{{u^2}}}{2}}}du,} $$ the bit error probability for a data rate of 500 kbps is How does 80386 change operation from real mode to protected mode? A motion control-system has type-2 plant. A recommended cascade compensation scheme for this system employs. What are the features of BiCMOS? Inversion layer in enhancement mode consists of excess of
