Questiоn 1 (10 pts = 5 questiоns x 2 pоints eаch) Choose the аppropriаte answers for the following questions. Write your choice clearly. If x(t) = A cos(ω0 t + φ), then A is: Phase Heart rate Angular frequency Amplitude Unwanted, often random modifications/additions a signal may suffer during capture, storage, transmission, processing, or conversion are called: Phase Noise DC offset Step function If x(t + T) = x(t) for a real constant T, then x(t) is: Odd Imaginary Periodic Even If x[n] = x[−n], then x[n] is: Odd Imaginary Periodic Even For a system S with input x(t) and output y(t), if a delayed input x(t + t0) produces y(t + t0), then S is: Linear Time-invariant Stable Causal
