NileSat Satellite transmits broadcastingprogram at Ku-Band (12 GHz). An engineer working in asatellite station complex has received the program by an earthstation and routed the signal through a rectangular waveguide ofdimensions (axb=2.4x1.2) to control room 12.2m away fromthe station feedhorn.(a) Which of the following modes can propagate:TE10 TE01 TE11 TM11 TE20 TE02show and confirm your work.(b) Calculate the characteristic impedance for the mode of the wave propagating down the guide.(c) Calculate the guide wavelength λg(d) If the waveguide made of copper (σ =5.7x107 mhos/m), calculate the total losssuffered by the signal at the control room.
Find the dimension of the window, as measured at the top of the oxide, after ideal isotropic etching (i.e. no overetch). Draw a cross section of the window opening with the resist still on.
1- Describe the function of the program. DO NOT WRITE THE OPERATION OF EACH INSTRUCTION 2- Assuming that the branch instruction is executed (the branch is taken), comput the number of clock cycles required to execute the loop (DECA or BNE AGAIN)
What is the maximum output resistance that the source follower must have if the output voltage is to remain within ±20% of nominal value. If the MOSFET has kn = 16 mA/V2, at what current ID must it be biased. At what overdrive voltage is the MOSFE..
A 5 KVA 480/120 V single phase transformer is to be used as an autotransformer to transform a 600 V source to a 480 V supply. As a single phase transformer delivering rated load at 0.8 PF Lag its efficiency.
To play music, these types of players have a decoder circuit that can decode the binary representation of the piece of music to be played. The electronic signals corresponding to the notes that are to be 'played' can then be transmitted to a speak..
Consider a signal x(t) = 10 cos(2pi*fct + 4 cos 2pi*fmt). Assume frequency modulation. The message frequency fm = 2:3 kHz. Calculate the modulation index and find the bandwidth when.
A message signal, x(t) has a bandwidth of 15 kHz and an average power of 0.5 W. This signal is to be uniformly quantized with an input range of range of +-5 V. What is the bit rate of the corresponding PCM signal if the SQNR is to be greater than ..
Four frequencies are applied at the input of anon-linear amplifier. Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics find out the frequency components at the output
The plant contains six 288MW generators. Given the overall facility efficiency is 76%, and the plant is capable of full output for a duration of 5 hours, determine the potential energy of upper reservoir and the minimum amount of water in gallons ..
A machine produces photo detectors in pairs. Tests show that the first photo detector is acceptable with probability 3/5. When the first photo detector is acceptable, the second photo detector is acceptable with probability 4/5.
An erbium-doped fiber amplifier has a noise figure of 4 and a gain of 10 dB. The optical input has a 30-dB signal-to-noise ratio and a signal power of 10 µW. Compute the output signal power in mW and signal-to-noise ratio (in dB) at the amplifier'..
A piece of germanium doped with 1016 cm-3 shallow donors is illuminated with light generating 1015 cm-3 excess electrons and holes. Calculate the quasi-Fermi energies relative to the intrinsic energy and compare it to the Fermi energy in the absen..
