1. What is the effect of sampling at a higher rate on the error performance of a digital modulation scheme?
2. Suppose 16QAM was the modulation scheme used for this lab; would the error performance for identical EbNo have been better or worse? You may want to write and implement the MATLAB code.
3. What mechanisms are available to the wireless design engineer to mitigate the effect of error generating noise? Of these mechanisms, some maybe unacceptable to the FCC, which are these?
Surface integral for jet engine. The air-gas exhaust velocity from a jet engine varies linearly from a maximum of 300 m/s at the center of the circular exhaust opening to zero at the edges. If the exhaust diameter is 1.6 m, find thq exhaust flow.
When the two windings are connected to a a.c supply of 50hz, the field current is 0.1A, the armature current is 100A and the phase difference between them is 60 degree. calculate the average torque and maximum torque.
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
The problem should be because Martians were using a non-decimal number system. Therefore, "50" is not fifty, but "50" in base b (50b=5×b+0×1=5b). The explorers reflected on the way in which Earth's number system developed.
This document is shown a paper on Orthogonal frequency-division multiplexing with advantages, disadvantages and uses.
Measurements on sodium have provided the following data: resistivity 4.7 ×10-8ohm m, Hall coefficient -2.5 × 10-10m3C-1, critical wavelength of transparency 210 nm, and density 971 kg m-3. Calculate (i) the density of electrons, (ii) the mobility, ..
Is there any advantage of star connection over delta w.r.t. induction motors? Also, is there any advantage or disadvantage of star connection over delta w.r.t. distribution and transmission of power? Please explain the reasons for all the advantag..
calculate the extraction efficiency and find the current and voltage needed to obtain the desired optical output. Once you know the current density choose Area and Find Vf that will give you the desired current density and current (If= Jf x A= Jn ..
Consider the transformer to deliver its rated kilovoltamperes at 0.80 power factor lagging to a load on the low-voltage side with 240 V across the load. Find the highside terminal voltage.
Improve the controller designed in part by introducing a mechanism for the disturbance compensation at the plant input. Illustrate advantage of the improved controller by applying the fast varying piecewise constant reference input vector and sinu..
