Unformatted text preview: 2 π, 2 π ] (b) Identify the symmetry of the signal and hence state ( without doing any calculation ) which Fourier coe²cients for this signal must be zero (c) Calculate the nonzero Fourier coe²cients. (1.5+1.5+3)=6 3. Consider a series RC circuit which has a timedependent voltage as its input which we call x ( t ). The output is identi±ed as the charge on the positive plate of the capacitor. (a) What is the equation relating the input and the output? (b) If the input is given by e jωt , then what is the response function H ( jω ). (c) Thus, if now an input x ( t ) = cos (3 t )2 sin (2 t ) is applied, what is the corresponding output? (1.5+2.5+3)=7...
