Consider the two feedback networks shown in Figures (a) and (b).
The 3 dB frequency of the amplifier A1 is 100 Hz and the 3 dB frequency of the second amplifier A2 is very large. The feedback transfer functions are β1 = 0.1126 and β2 = 0.0245.
(a) Determine the 3 dB frequency of each closed-loop network.
(b) What conclusion can be made as to the "better" closed-loop system?
Fix the number of users K (to, say, 30) and the number of receive antennas nr (to, say, 5). Plot the symmetric rate with SDMA, orthogonal multiple access and the intermediate access scheme as a function of SNR (0 dB to 30 dB). How does the interme..
Use round apertures centered across the broad wall of the waveguides.
The response of interest measured is the porosity of the resulting copper. Explain what type of study this is and why.
(c) Use a single 4-to-1 multiplexer with an active low enable and an active high output and a minimum of additional gates. Show the function expansion both algebraically and on a Karnaugh map.
Calculate the capacity of the phase advancing equipment. - calculate the annual saving effected.
