How can you build a Selective Gate? Using a presettable divide-by-N counter and a gating circuit that will gate the clock pulses from the clock. It should let three pulses pass and than block three.
Show that a Miller integrator implemented with an op amp with open-loop gain A0 has a low-pass STC transfer function. What is the pole frequency of the STC function. How does this compare with the pole frequency of the ideal integrator.
The noise temperature at the receiver antenna terminals is T0=290K. The equipment and environment suggest that 6dB of margin be used to assure performance under all conditions. For reliable voice communications, a received signal should be 17dB ab..
Suppose that data are stored on a 1.4-Mbyte floppy diskettes that weight 30 g each. Suppose that an airliner carries 10,000 kg of those floppies at a speed of 1000 km/h over a distance of 5000 km. What is the data transmission rate in bits per sec..
A magnetic flux of 400 microwebers passing through a coil of 1200 turns is reversed in 0.1 sec. Calculate the average value of the e.m.f induced in the coil. ( HInt use Faraday's Law)
A Rankine cycle power plant steam enters the turbine at 100psia and 800deg F.. Heat is rejected in the condeser at 80deg F. Isentropic sxpansion and compression occurs in the turbine and pump respectivel
a 14-bit successive approximation adc is used to sample a signal that has a full-scale range of 8V and a clock frequency of 12 MHz and a jitter of 50ns.initially this is used without a sample and hold amplifier.
An eight-point real-valued signal s has DFT given by S = [ 3 x1 4 -4+3j -2 x2 x3 1-2j ] A. Compute s[0] - s[1] + s[2] - s[3] + s[4] - s[5] + s[6] - s[7] using one entry of X only. B. Determine the values of x1, x2, x3.
Two particles are fixed to an x axis: particle 1 of charge q1 = 2.03 x 10-8 C at x = 16.0 cm and particle 2 of charge q2 = -4.62q1 at x = 77.9 cm. At what coordinate on the x axis is the electric field produced by the particles equal to zero
what is the change in capacitance for a diode with cross-sectional area of 0.01cm^2, dielectric constant of 11.8 when a change in the applied voltage gives a depletion distance change from 1/2 micrometer to 1 micrometer
find the fourier series coefficients of z(t) (use the results of a) and b) along with the multiplication property of continuous time fourier series coefficients). find the fourier series coefficients of z(t) through direct expansion of z(t) in tri..
