For both designs, the supply voltage is nominally 9 V and varies by +/- 1V. For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA. For the second design, assume that the current f
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.
