Questiоn 1 (10 pts = 5 questiоn x 2 pоints eаch): Choose the аppropriаte answers for the following questions. Write your choice clearly. 1. If two systems with impulse responses h1(t) and h2(t) are connected in parallel, the effective impulse response is: h1(t) + h2(t) h1(t) · h2(t) h1(t) − h2(t) h1(t) * h2(t) 2. Fourier series is convergent if: It has infinite period It satisfies Baptiste conditions It has infinite energy It satisfies Dirichlet conditions 3. A Fourier series decomposes a signal into: dc component sinusoids ac component exponential fractals 4. If y(t) = δ(t − τ) * h(t), then: y(jω) = H(jω) y(t) = h(t − τ) * δ(t) y(t) = h(t − τ) y(t) = −h(τ) 5. For a periodic function with period T0 and Fourier series coefficients ak, the Fourier transform X(ω) of the resultant aperiodic signal is an envelope of: Tk T0 a0Tk T0ak 6. For a system S that maps x(t) → y(t), if a delayed input x(t + t0) leads to a delayed output y(t + t0), then S is: Linear Time-invariant Stable Causal
