Two LTIC systems have impulse response functions given by h1(t)=(1-t)[u)t)-u(t-1)] and h2(t)=t[u(t+2)-u(t-2)].a) Carefully sketch the functions h1(t) and h2(t).b) Assume that the two systems are connected in parallel. Carefully plot the equivalent impulse response function hp(t).c) Assume that the two systems are connected in cascade. Carefully plot the equivalent impulse response function, hs(t).
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
Develop a voltage-to-current converter that satisfies the requirement I = 0.0021Vm. If the op amp saturation voltage is ±12 V and the maximum current delivery is 5 mA, find the maximum load resistance.
Laplace transforms enable interpretation and manipulation of different signals by viewing these signals as either time domain signals/pulse or else frequency domain representations
