3 friends get together once a week and vote on going to amovie or bowling. Majority vote wins. A '1' is a movievote. Design a logic circuit that automatically computes the decision: A) find the truth table & expression output of this circuit
Rotational and stray-lossesat full load are 5% of the output power. Calculate the power transferred across the air gap, the rotor copper loss at full load,and the electromagnetic torque at full nload innewton-meters.
If the input Voltage range of an ADC is from 0V to 5 V, and if 5-bit quantization is used, what is the size of each quantization step
Consider a vector field, F(r,theta,phi)= ar*cos^2(theta)/r^2 for the volume V of a spherical shell, centered at the origin,with inner and outer radii 1 and 2 meters. a) Evaluate triple integral delta.F dv over v. b) Calculate also the closed surface ..
A DSP engineer applies DFT to 500 data samples that are sampled at 250 Hz to plot the signal spectrum. What is the frequency that corresponds to the frequency bin number
the z-axis carries a 10mA current in the +z direction. A second line of current parallel to the first is located at x= 0, y=3cm carrying a 10 mA current in the -z direction. A rod exists in the y-z-plave from y= 1cm to y= 2 cm. velocity u = 2m/s z..
Calculate the current through a 1 mF capacitor in response to a voltage v if across its terminals, if v equals (a)30te-tV (b) 4e-5tsin100t V
Design a circuit that will indicate the birth months of February, April and May. The month is specified by a 4-bit input, A3:0. For example, if the input bits are 0001, the month is January and if the inputs are 1100, the month is December.
Find the current change brought about by subjecting a 1 mH sinductance to a voltage pulse having an amplitude of 1V and a duration of 1 ms.
Describe how you would use the combination of a short pass filter, a long pass filter, an amplifier and a mechanicalchopper to amplify a 5 mV signal to a 50 mV signal and remove noisefrom the original 5 mV signal.
Calculate the inductive reactance per meter of a single-phase, 50-Hz, two-wire transmission line. Assume each conductor's radius is 6cm and the distance between the two conductors is 3m.
1. Consider the Nordex 1.3MW, 60-m wind turbine with power specifications given in table 6.7 located in an area with 8m/s wind speeds. a) find the average speed in the wind (W/m^2) assuming Rayleigh statistics.
