What refractive index and what thickness do you need to make aquarter-wave anti-reflection coating between air and silicon at10GHz? At λ0= 10μm? Assume undoped silicon with losses negligible.
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
Using the message signal m(t) = 1/(1+t^2) , determine and sketch the modulated signals for the following methods of modulation: (c) SSB modulation with only the upper sideband transmitted. (d) SSB modulation with only the lower sideband transmitted.
The heating element in a soldering iron has a resistance of 30-ohm. Find the average power dissipated in the soldering iron if it is connected to a voltage source of 117 V rms.
Basics problems of Induction motor, The frequency of the induced rotor currents in the rotor of a 60 Hz induction, machine is 2 Hz. Furthermore, the fields in the air gap turn at -40 rpm with respect to the rotor.
A military satellite uses 10 GHz for the downlink frequency. The distance to the satellite is approximately 36000 km. if the satellite transmitter produces a power of 50 dBm with a transmit antenna gain of 20 dB and on the ground
signal s(t)= (2a) / (t2+a2) A) Determine the essential bandwidth B Hz of s(t) such that the energy contained in the spectral components of s(t) of frequency below B Hz is 99% of the signal energy.
The electric motors unmanned drones use transformers to produce sufficient current to move the flight surfaces. Due to the weight restrictions of the vehicle, the transformers use a ceramic rather than iron, the ceramic has a permeability of mu = 4..
Suppose you are told that a Moore machine has five flip flops, three inputs and nine outputs. What is the minimum and maximum number of states in the state diagram, the minimum and maximum number of transition arrows at a particular state
A 60-Hz, 765-KV three-phase overhead transmission line has four ACSR 900 kcmil 54/3 conductors per phase. Determine the 60-Hz resistance of this line in ohms per kilometer per phase at 50 degrees Celsius.
Explain how primitive values like doubles are passed between functions in Java. How are string objects passed between functions in Java How are static methods different from non-static methods How do you invoke a static method
