A radio wave that may be considered a uniform plane wave propagates through the ionosphere and interacts with some charged particles which are moving with a velocity a tenth the velocity of light in the direction normal to the magnetic field of the wave. Find the ratio of magnetic force of the wave on the charges to the electric force.
An LED with a rated range of Vf = 1.4 V to 1.8 V at If = 20 mA is connected to a driver circuit with a peak output of 14 V. What value of current. limiting resistor would be needed to limit the LED current to a maximum value of 20 mA.
The transfer function (TF) of a system is given below. Find its impulse response inn domain. Hint: First multiply the TF by the z-transform of input-or x(z)-or the z-transform of unit impulse. Factor the denominator and then expand.
A three-stage amplifier is shown. The operating bandwidth is 500 KHz at a temperature od 25 degrees C. The output load is 1000 ohms. calculate the total NF as a number, calculate the output noise power, and calculate the output noise voltage.
Light is incident from air to glass at Brewster's angle. Determine the incident and transmitted angles. Glass has refractive index n2=1.45.
Determine whether the system described by (1) y[n]=log(nx[n]), (2) y[n]=sqrt(n)*x[n+1], (3) y[n]=x[n-2]u[n], where a is an integer and |a|>1, is (i) memoryless; (ii) invertible; (iii) causal; (iv) stable; (v) time invariant; (vi) linear
Why are overmodulated and carrier suppressed AM signals a problem from the standpoint of the receiver. Why (in what siuations) might DSB-SC be prefered over standard AM.
The can's initial volume at 5 °C is 7.2 × 10-4 m3. The coefficient of volume expansion for aluminum is 69 × 10-6 (C°)-1. When the can and the liquid are heated to 87 °C, 7.0 × 10-6 m3 of liquid spills over.
A signal is sampled every 1ms for 20ms, with the following actual values of the analogue voltage at successive sampling times. Plot the values of the voltage recorder by a 5 volt, 4 bit ADC assuming that the noise level is much lower
Complex Voltage = 10-j20. try to convert it to polar coordinate with my Ti 89 but I keep getting my answers in arc tan.
Fourier transform X(w)=Xreal(w)+j(Xi(w)). Determine and represent the signal y(w) that gives the fourier transform of Y(w)=Xi(w)+Xreal(w)e^exp(j2w).
Two Si samples are doped n-type and p-type such that they have the same resistance. If the electron and hole mobilities are respectively 1350 and 450 cm2/Vs, find the relative values of Na and Nd.
An ideal non-degenerate silicon step junction diode with an intrinsic level Ei exactly at mid band-gap is fabricated. Answer all questions related to this diode. a) If Vbi = 0.65V and NA=4ND, what is the doping concentration in the quasi neutral n ..
