1. Tell me what you know about how a tenth-order lowpass Chebyshev filter is implemented. Your discussion should include the center frequencies and Qs of the stages.
2. To get a fast roll-off and a linear-phase response, somebody has cascaded a Butterworth filter with an all-pass filter. Tell me what each of these filters does.
3. What is an MFB filter and where is it used?
in step index fiber the core of diameter D has a refractive n1, which is typically equal to 1.48. core is typically surrounded by the cladding of slightly lower index. Where n2=n1(1-delta). The parameter is simply called the index difference.
It is required to design an amplifier to have a nominal closed-loop gain of 10 using a battery operated amplifier whose gain reduces to half its normal full-battery value over the life of the battery.
Derive the Helmholtz's wave equation. Start your derivation from Maxwell's equations.
In an amplifier circuit, why do we need to bias the MOSFET atan operating point What would happen if the signal peak amplitudewas smaller than 1 V, the transistor had Vto=1 V and we biased the transistor at Vgsq=0
a 1.5 V battery will deliver 9mA for a continuous 38 hrs. during that time the voltage drop will be from 1.5 to 1.0 V. Assume the voltage drop is linear. How much energy does the battery deliver over the 38 hr interval
a positive test charge is used to explore the field of asingle positive point charge Q at P(a,b,c). if the test charge isplaced at the origin, the force on it is in the direction0.5ax-0.5sqr(3ay), and when the test charge is moved to (1,0,0)
If possible, compare your results to those obtained from a microwave CAD tool.
A reservoir-type small hydroelectric system has an effective head of 10m and a penstock of a flow rate of 1m3/s. Assume that the hydro efficiency is 85%, the turbine efficiency is 80% and the generator efficiency is 92%; compute the output electri..
Knowing that the average allowable shearing stress in the bolts is 90 MPa, determine the largest permissible vertical shearing force.
If the amplifier is fed from a voltage source Vsig having a resistance Rsig = 1kΩ, find the transfer funtion Vo/Vsig as a function of the complex-frequency variable s and hence the 3-dB frequency fH and the unity-gain frequency ft.
Two homogeneous isotropic dielectrics meet on plane x=0. For x > 0, Er1=6 and for x 0. Find: a) E2 for x
What are the names of the three regions of the bipolar junction transistor? Why is there a thin region of one material type
