A signal $$2\cos \left( {{{2\pi } \over 3}t} \right) - \cos \left( {\pi t} \right)$$ is the input to an LTI system with the transfer function $$H\left( s \right) = {e^s} + {e^{ - s}}$$ If C k denote the k th coefficient in the exponential Fourier series of the output signal, then C 3 is equal to What is the ROC for the given signal? $${x_1}\left[ n \right] = {\left( {\frac{1}{2}} \right)^n}u\left[ {n - 3} \right]$$ Source encoding in a data communication system is done in order to A reflex klystron is oscillating at the frequency of its resonant cavity. If the reflector voltage is made slightly less negative, the The response of an initially relaxed linear constant parameter network to a unit impulse applied at t = 0 is 4e -2t u(t). The response of this network to a unit step function will be
