I have the following problem:
Design a digital system transmitting a 4-Gbps NRZ signal over a 100-km path without the use of repeaters. The error rate must be 10^-9 or better.
My first step is to find the total system rise time which is:
.7 / (4x10^9) = .175ns
the selected fiber must have a...
I have a Zo=50Ω transmission line that is (3λ/4) long (quarter wave transformer)
I have connected it to a 5V source with a Zg=100Ω impedance on the left side.
On the right side, it is terminated with a Zl=100Ω impedance.
I know that Zin=50²/100=25Ω
Can I model this circuit as a 5V source in...
My problem is:
Find the ranges of the dimensions a and b of a rectangular waveguide filled with dielectric e=2.56e0 with (u=u0) under the conditions that
-TE10 mode propagates with a 20 % safety factor (f=1.2fc)
-the frequency is at least 20% below the cutoff frequency of the next higher order...
I am working on a problem but am having great difficult trying to plot
|Tin| vs Δf/fo.
The Problem is as follows
Design a dielectric resonator oscillator using the series feedback circuit with a coupling factor of .1, for a wireless are network application. This local oscillator operates as...
Finding ERP (EIRP)
I have the following problem that I have worked on for too long and have still not been able to come up with the answer.
A DBS Reflector Antenna operating at 12.4 GHz with a bandwidth of 20 MHz has a diameter of 18" and an aperature efficiency of 75%. A noise temperature of...
Calculating Stability
I have the following S-Parameters
S11=1.2<-60 S12=.2<120 S21=3<60 S22=.7<-60
I am using the K-Δ test to check for stability
I calculated Δ to be .75<-76
I calculated K to be -.30625.....?!? Is this possible. I have checked all of my formulas and calculations...
