A certain engine lathe can be purchased for $330,000 and depreciated over three years to a zero salvage value with the SL method. This machine will produce metal parts that will generate revenues of $220,000 (time zero dollars) per year. It is a policy of the company that the annual revenues will be increased each year to keep pace with the general inflation rate, which is expected to average 5.5% per year. Labor, materials, and utilities totaling $55,000 (time 0 dollars) per year are all expected to increase at 10% per year. The firm's effective income tax rate is 43%, and its after-tax MARR (im) is 26% per year. Determine the after-tax equivalent present worth. Use life of three years and work to the nearest dollar.
Frequency Range, Local Oscillator Frequency, Image Frequency, and Attenuation, A radio receiver for the AM broadcast band covers the frequency range 550 to 1600 kHz. The IF frequency is 455 kHz and the local oscillator is above the received signal..
Write the formula for the magnetization volume current density J M and magnetization surface current density JMS in terms of magnetization vector M. 4. A sphere has permanent magnetization where is a positive constant.
The following measurement were made on a two-port resistive circuit. With port 1 open, V2 =15V, V1 = 10 V, and I2 = 30 A. With port 1 short-circuited, V2 = 10 V, I2 =4 A, and I1 = -5 A. Find the parameters of the z-parameter two-port.
The signal m(t)=6sin(2*pi*t) volts is transmitted using 4-bit binary PCM system. The quantizer is of the midriser type, with a step size of 1v
Consider a signal x(t) = 10 cos(2pi*fct + 4 cos 2pi*fmt). Assume frequency modulation. The message frequency fm = 2:3 kHz. Calculate the modulation index and find the bandwidth when.
a) construct the straight-line Bode plot of the gain. Is this a low-pass, high-pass, bandpass, or bandstop function b) Use the straight-line plot to estimate the maximum gain and the frequency at which it occurs.
Evaluate the TL parameters. Include the effect of the earth as ideal. Do not incorporate the effect of the shield wires.
Design an interface for a ±24 V, 500 mA geared DC motor. The time constant of the motor is 10 ms. Include software to adjust the delivered power from 0 to 100%.
draw the sympol and truth table of the gate that corresponds to the action of the logic gate.
Create a program using AsmIDE, which utilizes the Fox 11 68HC11 microcontroller board: Speech timer where max time is 5 minutes Use the switches for:
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
