Jack understands that levodopa is the mainstay of treatment for Parkinson disease and asks the NP why he is on the combination drug carbidopa/levodopa. What would be the best explanation the NP could give Jack on why the dopaminergic agent carbidopa/levodopa is more effective than the dopaminergic agent levodopa alone in minimizing the symptoms of Parkinson disease? When used together, they inhibit the enzyme dopa decarboxylase in the periphery, diminishing the metabolism of levodopa in the GI tract and in peripheral tissues, which leads to higher levels of the drug crossing the blood-brain barrier When used together, they prolong the effect of levodopa by blocking an enzyme, COMT, which eliminates dopamine and increases the plasma concentrations and duration of action of levodopa When used together, they act to increase the level of ACh in the CNS by inhibiting its breakdown and slowing neural destruction When used together, they block certain neurotransmitter receptor sites, which potentiates the effects of the inhibitory transmitter gamma (y)-aminobutyric acid (GABA)

The continuous-time signal $x_a(t) = \cos (150\pi t)$ is sampled with sampling period $T_s$ to obtain a discrete-time signal $x[n] = x_a(nT_s)$. 1. Compute and sketch the magnitude of the continuous-time Fourier transform of $x_a(t)$ and the discrete-time Fourier Transform of $x[n]$ for $T_s = 1$ ms and $T_s = 2$ ms. 2. What is the maximum sampling period $T_{s,max}$ such that no aliasing occurs in the sampling process?
