1. In class we found that the Fourier series of a unit amplitude square wave of period 2 seconds was given by (a) Show that this series can be rewritten as 0o 2 (b) Produce plots of x (t) for n-1 to N for N-1,3,9,19,and 199, that is, truncate the infinite sum to these values of N and plot the result. Remember that only odd terms are included in the sum...
signals and systems (power and energy signals) Q) Prove that the power of an energy signal is zero over infinite time. Also, prove that the energy of a power signal is infinite over infinite time.

3. Sketch stuff (by hand or by computer) 3.1 Systems signals The signal x()-sin^t), for 0stsl; is applied to a circuit with an impulse response given by h(t)-2, for Osts1. Sketch these signals and the output of the circuit If the input signal is now set to x()-6(t-3), sketch the input and output signals. (3.2)
