DSSSConsider a direct sequence spread spectrum (DSSS) system attempting to transfer data. The DSSS system has a data rate of 2 Kbps (2 thousand bits/sec) which is spread to 2 Mcps (two million chips per second). How much would be the processing gain:
a) 30 dBb) 20 dBc) 100 dBd) 60 dB
A batch process which involves filling a tank with liquid, mixing the liquid and draining the tank, is automated with a PLC. The specific sequence of events is as follows
Analysis of link budget DTH QPSK Satellite link, A direct-to-home satellite television system uses a geostationary satellite in orbit above the equator at a longitude of 109 degrees west.
What is the shape of the spectrum of the signal? What is the extent of the spectrum in the frequency domain? What is the unit that is applied to the magnitude of the spectrum?
Assume the initial state is steady (y = 0 at t = -0) a) Determine the transfer function of this process in the s domain. b) If the input is a ramp change in u(t) = 4t, determine the value of y(t) when t = 10s.
What are some of the possible biases and points of error that may arise in team communication systems and what are the advantages and disadvantages of a transactive memory system (TMS) in a team
And how long it will take to reach that temperature assuming no heat lost in the process and comments on your results and may research the properties of nichrom wire to determine the resistivity of the wire
Design a series controller (a PD, PI or PID) so that the following performance specifications are satisfied. Steady-state error due to a step input = 0
You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.
A shunt regulator utilizes a zener diode whose voltage is 5.1V at a current of 50 ma and whose incremental resistance is 8 ohms. The diode is fed from a supply of 12 V nominal voltage through a 220 ohm resistor
