Identifying developmental milestones is an important skill set for ARNPs for which of the following reasons? Group of answer choices Often developmental milestones go unrecognized until a child is much older. Knowing when a significant variation in development has occurred improves diagnostic accuracy. The sooner a significant developmental impairment is identified and addressed, the better the long-term outcomes could be for patients. All of the above.

[35 pts] Problem 3) A frequency modulated signal is denoted by the following equation: $\phi_{FM}(t) = 10 \cos(3\pi \times 10^4 t + 0.01 \sin(2000\pi t))$ (a) Find the power of the modulated signal. (b) Find the carrier frequency $f_c$. (c) Find the frequency deviation $\Delta f$. (d) Find the deviation ratio $\beta$. (e) Find the phase deviation $\Delta \phi$. (f) Estimate the bandwidth of $\phi_{FM}(t)$. (g) Assuming (only for this question) that the $k_f$ of the frequency modulator equal to 31.416, what will the PM representation of this signal be if the PM modulator has a $k_p$ equal to 0.2 and a carrier signal similar to the FM modulator.

Consider a very long solenoid of radius a and n turns of coil per unit length, carrying current I(t) = I<sub>0</sub>sin(?<sub>0</sub>t), where I<sub>0</sub> and ?<sub>0</sub> are constants. What is the induced magnetic field, \vec{B}<sub>ind</sub>(\vec{r}, t), both inside and outside the solenoid? Remember: you will use the analog of Faraday's Law, replacing the magnetic flux with the (induced) electric flux, and choosing the loop for your line and surface integrals carefully. N.B. You will really only be able to derive the induced magnetic field up to some unde- termined \"constant\" (it will have no spatial dependence, but will have time de-pendence) that corresponds to \vec{B}<sub>ind</sub>(\vec{r}, t) at some specified reference location, such as the axis of the solenoid (\vec{r} = z\hat{z}, or s = 0). Also, don't worry that you did something wrong if you find that the induced magnetic field doesn't fall off to zero as s ? ?. Our use of the quasi-static approximation means our solution is only valid for points \"near\" the solenoid.
