Q1) Consider the circuit shown below. One end of the switch is fixed on point 'a'. The other end of the switch was on point '1' for a long time before t = 0. At t = 0, the switch is moved from point '1' to point '2'. Then, at t = 10ms, the switch is moved from point '2' to point '3'. Calculate the voltage drop, v(t), on the 1 uF (micro-Farad) capacitor for t ? 0. Please solve for v(t) for each phase and draw v(t) for t ? 0 as clearly as possible.

Two baseband signals $m_1(t)$ and $m_2(t)$ whose spectrum are shown are combined to form the composite signal $m(t)$, which is used to modulate a 100-MHz carrier to obtain the output modulated signal $\phi(t)$ as shown in the figure below. $\cos(2\pi f_1 t)$ $M_1(f)$ $m_1(t)$ -10kHz 0 10kHz $m(t)$ +$\phi(t)$ $M_2(f)$ $m_2(t)$ $\cos(2\pi f_2 t)$ -10kHz 0 10kHz $\cos(2\pi f_2 t)$ Let $f_1 = 30\text{ kHz}$ and $f_2 = 10\text{ kHz}$. a) Sketch the spectrum of $m(t)$ and determine its bandwidth in Hz. b) Determine the bandwidth of $\phi(t)$ in Hz. c) Sketch a block diagram of a possible receiver to recover $x_1(t)$ and $x_2(t)$ individually from the modulated signal $x_c(t)$. Also indicate the type of filter (lowpass or bandpass) and the bandwidth of any filters that may be required.

7. [1/2 Points] DETAILS PREVIOUS ANSWERS SCALCET9 6.1.058. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER If the birth rate of a population is $b(t) = 2000e^{0.024t}$ people per year and the death rate is $d(t) = 1470e^{0.019t}$ people per year, find the area between these curves for $0 \le t \le 10$. (Round your answer to the nearest integer.) What does this area represent in the context of this problem? This area represents the decrease in population over a 10-year period. This area represents the increase in population over a 10-year period. This area represents the number of deaths over a 10-year period. This area represents the number of births over a 10-year period. This area represent the number of children through high school over a 10-year period. Need Help? Read it
