Suppose that a sinusoidal input g(x,y)=cos[2*pi(x*fx+y*fy)] is applied to a linear system. Under what (sufficient) conditions is the output a real sinusoidal function of the same spatial frequency as the input? Express the amplitude and phase of that output in terms of an appropriate characteristic of the system
