The access time for a cache memory is one tenth the access time for the main memory. If the hit ratio is 0.9, then the effective access time is
What focal length should a pair of contact lenses have if they are to correct the vision of a person with a near point of 57.3 cm Assume that the near point distance is 25 cm.
You have two biased coins. Coin A comes up heads with probability 1/4. Coin B comes up heads with probability 3/4. However, you are not sure which is which so you flip each coin once where the first coin you flip is chosen randomly.
Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010
A three-phase ,600MVA,13.8KV Ac generator has a synchronous reactance of 2.0 per unit. The generator is connected to a system for which specified base fare 100MVA and 345KV.
When electros and holes are present in a semi-conductor, the presence of an electric field produced by an external voltage will cause this carries,which have changes of oposite sign, to move in opposite directions.
A first-order allpass filter impulse response is given by h(t) = - d(t) + 2e^(-t)*u(t) a) find the zero-state response of this filter for the input e^(t)*u(-t). b) sketch the input and the corresponding zero-state response.
The electron and hole concentrations as a function of energy in the conduction band and valence band peak at a particular energy. Consider silicon and assume Ec - EF =0.20 eV. Determine the energy, relatiive to the band edges
Two components of linear distortion produced by transmitting asignal through an LTI (linear time invariant) system: Amplitude distortion - the frequency components of the input signalare transmitted through the system with different amounts of gain..
A 75-kVA, 230-V/115-V, 60-Hz was tested with these results: Open-circuit test: 115 V, 16.3 A, 750 W; Short-circuit test: 9.5 V, 326 A, 1200 W a) Determine the voltage regulation at rated load, 0.8 power factor lagging.
Compute the power absorbed by an element in a circuit, but for a simple sinusoidal current i = sin(2πt/T) where T = 1 s.
The signal x(t) = 2 - sin(4.5t - pi / 4) + 3 cos (24t + pi / 2) is input into a system with frequency response H(omega). Find the output signal y(t) if: H(omega) = rect(omega/80) H(omega) = 2 - 2rect(omega/8) H(omega) = sin c(omega/20)
A certain coaxial cables is designed to handle extremely high voltages. In order to prevent dielectric breakdown the electric field (E-field) must be minimized.Calculate the correct value of B to A to minimize the electric field.
