Question

blood samples taken every 15 minutes.

Density h [n] = (0.917) ^ n.u [n] mg / liter.
a) Write the difference equation. Draw the representative block diagram of the system consisting of delay elements, fixed multipliers and addition elements.
b) Find the half-life (when the density is reduced to half) of the drug.
c) Determine if the system is FIR or IIR. Examine the system stability.
d) If the drug was administered as x [n] = u [n] mg / l, what would be the highest drug concentration in the blood and when would this value ? + 1 be reached?
