Question 5: (30 pts) For the common-emitter amplifier shown below, let $V_{cc} = 15V$, $R_1 = 27 k\Omega$, $R_2 = 15 k\Omega$, $R_E = 2.4 k\Omega$, $R_C = 3.9 k\Omega$. The transistor has $\beta = 100$. (note: Early effect is ignored.) 1) Calculate the dc bias $V_B$ and $V_E$; 2) Calculate the dc bias current $I_C$ and $g_m$; 3) If the ac amplifier has $R_{sig} = 2 k\Omega$ and a load of $R_L = 2 k\Omega$: a) Draw the equivalent ac circuit diagram using the BJT's hybrid-$ \pi $ model circuit; b) find the base resistor $r_\pi$ and the overall voltage gain $v_o/v_{sig}$

The Lynx- Snowshoe Hare Relationship The ten-year cycles of the populations of the snowshoe hare and Canada lynx was first recorded from fur returns of Hudson's Bay Company traders in the late 1800s. The cycles revolve around the lynx's preference for hares over other animals as a food source. This predator-prey relationship is again being studied by the Northwest Territories Department of Renewable Resources, in an area known as the Mackenzie Bison Sanctuary. Lynx Population in the Mackenzie Bison Sanctuary 1991 1992 100 km. N = 19 100 km. The population density in 1991 is 100 km. Legend: = 1 Lynx Lynx/km² 100 km N=3 Activa Go to Se
