a parallel RLC circuit consists of a 2.2 uF capacitor and a 3.3 mH inductor.
a) select a resistor (R1) such that the circuit will be critically damped. Draw the circuit
The initial voltage across the capacitor is 5V and the initial current through the inductor is 100 mA. A switch is thrown at t=0 such that the circuit is connected in parallel with a 50 mA independent current source. Assume that the reference direction for the current source points toward the positive circuit node and that the reference direction for the inductor current points toward the negative circuit node.
b) Find the expression for the critically damped voltage response: V1(t)
c) Replace R1 with an R2=.5(R1). Find the expression for the response: V2(t)
d) Replace R2 with an R3=2(R1). Find the expression for the response: V3(t)
Male frogs give calls that attract female frogs to approach and mate. Researchers examined mating calls of closely related tree frogs in South America. If reinforcement of postzygotic isolation is occurring
A certain transmission line is 10 meters long. Measurements indicate that the total inductance of the cable is 16 H. Standing wave measurements indicate that the voltage reflection coefficient at the load is 0.5 + j0 when a 75 ohm resistor
A 4 MHz time-harmonic uniform TEM plane wave that is traveling through a lossy nonmagnetic medium has an amplitude that attenuates by 20% for each meter of propagation. The electric field of the wave leads the magnetic field by 35°
Note that after a collision, the expected numbers are slightly different in two systems, but the difference is unimportant since collisions are rare.
1)Design the following function in BiCMOS using the least amount of transistors (RTL not allowed). z= (AB)' + (CD)' 2)Calculate the Emitter current through a loading Resistance of 10k such that VOH=2.3V.
