A microwave resonator is connected as a one-port circuit, and its return loss is measured versus frequency. At resonance the return loss is 14 dB, while at 2.9985 GHz and at 3.0015 GHz the return loss is 11 dB (the half-power points). Determine the unloaded Q of the resonator. Do this for both series and parallel resonators.
What can you say about the impedance of a parallel RLC circuit at the resonant frequency? How is the resonant frequency defined? Compare the definition of quality factor for the parallel resonant circuit with that for the series resonant circuit.
A perfect inductor with L = 0.2 H is connected in series to a voltage source with: v(t) = 10cos(40pi(t) 20degrees). What is the reactance of the inductor
The building has 49 stories and there are up to 600 devices on each floor. To alleviate traffic on the fiber backbone, you want each floor to be its own subnet. Just list the first three and last two valid network ID's & address ranges
Design a first-order digital highpass chebyshev filter (.5-db ripple) with a cutoff frequency of 850 Hz and a sampling frequency of 10 kHz. Determine the transfer function using BLT.
Determine the improvement (in decibels) in the output SNR that results if the modulation index is increased from 0.6 to 0.9.
The power delivered to the element is p(t) = 4.9e-8t W. Compute the current in the element as a function of time, the voltage across the element as a function of time, and the total energy delivered to the element in the time interval 0
The surface concentration is fixed at N0=1.8e20/cm^2 when diffusing boron into a uniformly doped n-type substrate. The atomic diffusion constant for boron in Si at the temperature of 950 C is 3.0e-15 cm^2/s.
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.
Often when developing a new wireless digital communication protocol it is useful to develop a simulator to evaluate the various methods available for communication of the data.
The Type-1 Chebyshev filter is known to provide the lowest deviation in passband for a given filter order. The transfer function for the second order analogue low pass 3-dB passband ripple Chebyshev-1 filter is given by the following expressi..
Consider a gsm uplink.the ms has 100 mw transmit power and the sensitivity of the bs receiver is -105 dbm.the distance between the bs and ma is 500 m.the propagation law follows the free space law up to a distance of dbreak=50m
Consider the parallel inductors shown in Figure P3.61, with mutual coupling and the dots at the top ends of L1 and L2. Derive an expression for the equivalent inductance seen by the source in terms of L1, L2, and M.
