Design a band pass filter using three quarter-wave short-circuited stub resonators. The filter should have a 0.5 dB equal-ripple response, a center frequency of 3 GHz, a 20% bandwidth, and an impedance of 100 . (a) Find the required characteristic impedances of the resonators, and use CAD to plot the insertion loss from 1 to 5 GHz. (b) Lay out the micro strip implementation of the filter on an FR4 substrate havingr = 4.2, d = 0.079 cm, and tan δ = 0.02, and with copper conductors 0.5 mil thick. Use CAD to plot the insertion loss versus frequency in the pass band of the filter, and compare with the lossless case.
A coaxial cable has an inner conductor of radiua a = 0.8 mm and an outer conductor of radius b = 2.6 mm. The conductors have σc=5.8x10^7 [S/m] uc=uo. ε=ε0 they are separated by a dielecric material having σ = 10^-5[S/m], u = uo, ε=3.5ε0.
Objective: Develop a digital logic circuit utilizing the skills gained in EE202 to create a circuit capable implementing a Hamming error correction code. Description: The data transmitted through you're the system is stored in 8 bit (1 byte) words. I..
1. What happens to both resolution and full-scale output when the reference voltage on a DAC is increased by 20% a. resolution gets better by 20%, output goes down by 20% b. resolution gets worse by 20%, output goes up by 20%
What kind of transistor has higher voltage gain, BJT or FET and why What kind of transistor has better noise response BJT or FET and why How about frequency response high frequency, FET or BJT Low frequency response, FET or BJT

a boatman must carry a wolf a goat and a cabbage across a river in a boat which is so small that he can carry at most
Suppose instead that the current is only about 100,000 A. Then theoretically we should expect that only 100,000/(2*F)=0.52 moles of hydrogen is going through the system. However, due to leakage, crossover, and other losses the theoretical amount i..
