The voltage across an element is 12e to the power of -2t . The current entering the positive terminal of the element is 2e to thepower of -2t .Find the energy absorbed by the element in 1.5 s starting from t=0
i) Calculate the number of calls/hour/cell and the number of calls/hours/km2 ii) Calculate the number of users/hour/cell and the number of users/hours/channel iii) Find the modulation frequency for this system.
A receive antenna located at 1km from the transmitter has a gain of 5dBi. Assume that there are 2dB of system loss.A. If the system operates at 900MHz, what is the power level at the output of the receive antenna terminals
Create the layout design for MOS inverter using a depletion-type transistor with VTL = -0.3V and an enhancement-type device with VTO = 0.5V such that tPLH is less than or equal to 15ns and tPHL is less than or equal to 1ns with CL = 1pF.
Laplace transforms enable interpretation and manipulation of different signals by viewing these signals as either time domain signals/pulse or else frequency domain representations
The fiber has a loss of 0.25 dB/km, and there is a splice with a loss of 0.1 dB every km. The coupling loss at the receiver is 0.5 dB, and the receiver uses an InGaAs APD with a sensitivity of -39 dBm. Find the system margin.
An amplifier output is being evaluated by a technician. The output is found to be a sine wave. The measured time lapse from one sine-wave peak to the next is 5 milliseconds.
We use the time constant to characterize transients in electric circuits. In physics, the half-life is often used to characterize the exponential decay of physical quantities such as radioactive substances.
The input to a certain filter is given by Vin(t)=2cos(10000pi*t-15deg) and the steady state output is given by Vout(t)=5cos(10000pi*t+25deg). Determine the (complex) value of the transfer function of the filter for f=5000 Hz.
If a RAM memory has a 5-to-32 row address decoder and a 6-to-64 column address decoder, and eight pins I/O, what is the size of the memory
A coiled tungsten wire of diameter 50um and length 10cm is glowing at a temperature of 2000°C within an evacuated light bulb. Determine the irradiance of the filament and the fraction of irradiance within the visible range of wavelength.
which semiconductor device and circuit technologies made the wide spread of mobile communications possible How modern electronics technology affects positively and negatively your personal life, the work environment and the global society
An infinitely long wire is placed in a space with relative permeability of 9000 carrying current of 1.9 A in the +y direction. What is the magnitude of the magnetic flux density at (0.03,0,0) [meters] in units of Tesla
