A 0°-inclination LEO satellite will use TDRS (at geostationary orbit) to regularly communicate at S-band (assume 2.2 GHz) to Earth. The satellite orbits at an altitude of 400 km. What minimum tracking bandwidth must the TDRS receiver possess in order to accommodate the Doppler effect? (Hint: you need to include both the velocity of the LEO satellite and the velocity of the GEO satellite. To the LEO satellite, the GEO satellite is not standing still.)
Draw a 4-bit Linear Feedback Shift Register using a final transition/excitation equation of Q3+ = D3 = Q1 Q0. Determine the sequence generated from this circuit. How many states does the circuit cycle through when given an initial state of 0001
If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
A 60-Hz, single-phase transmission line has a length of 80 miles. Its shunt conductance (G) is 3.4×10?11 S/mile, resistance (R) is 0.1 ?/mile, capacitance (C) is 16 pF/mile, and inductance (L) is 0.56 mH/mile.
Power Factor, A single phase electric motor has an output power of 10 kW and an efficiency of 90% at full load. The motor is fed from a 240 V supply via a cable that has a resistance of 10 milli ohms per metre length.

Two rectangular waveguides, one air filled with internal dimensions 2cm x 1cm and the other dielectric filled with internal dimensions 1cm x 0.5cm, have the same cut-off frequency for the dominant mode. what is The relative permittivity of the die..
Suppose a certain causal signal f(t) has a Laplace transform F(s) = 1. If f(t) is sampled at times kT where T is a constant time interval and integer k>=0, what are the sample values
A cloud company has 20 computers total. Out of the 20 computers, 9 run web servers and 12 host databases. Furthermore, 8 machines offer file sharing. Note that a particular machine can offer multiple services.
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 100 , inductive reactance XL = 200 , and capacitive reactance XC = 200 . All three components are connected in parallel to the source.
Develop a Sensor Circuit using commodity component and design a wireless sensor node using commodity wireless modules
Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
