An injection-molding machine can be purchased and installed for $90,000. It is in the seven-year GDS property class and is expected to be kept in service for eight years. It is believed that $10,000 can be obtained when the machine is disposed of at the end of year eight. The annualvalue added that can be attributed to this machine is constant over eight years and amounts to $15,000. The company uses an effective income tax rate of 40%, and the after-tax MARR of 15% per year. a) What is the approximated value of the company's before-tax MARR? b) Determine the GDS depreciation amounts in years on through eight. c) What is the taxable income at the end of year eight that is related to capital investment? d) Set up a table and calculate the ATCF for this machine e) Should a recommendation be made to purchase the machine?
What is the minimum output voltage of the Ratio detector. When the maximum discriminator output voltage is fed into an audio amplifier, the amplifier drives 100 Watts into an 8 ohm load. What is the dB gain of the audio amplifier.
A filter with a great deal of attenuation must be placed in an amplifier chain. Ignoring all considerations other than the desire to minimize noise figure, would it be preferable to put the filter before or after a low noise amplifier Why
A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.1 x 10-3 s, and the force of the kick is given by F(t) = [(6.1 x 105)t - (2.3 x 108)t2] N for 0 t 1.1 x 10-3s, where ..
When fed from a signal source with a peak amplitude of 0.1v and a source resistance of 20k , the peak amplitude v(pi)is 5mv. specify Re and bias current Ic. The BJT has beta =100. If the total resistance in the collector is 5 k,
An 8x1 multiplexer has inputs A, B, and C connected to the selection inputs S2, S1, and S0, respectively. The data inputs I0 through I7, are as follows: I1 = I2 = I7 = 0; I3 = I5 = 1; I0 = I4 = D; and I6 = D'. Determine the Boolean function that t..
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
Design an RC-Low Pass Filter with cutoff frequency at fc=0.5GHz and plot its frequency response and design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence.
What is the maximum symbol rate for this link and the number of bits per symbol? What format would you recommend for the transmitted current pulses on this baseband link?
Calculate the magnitude and phase angle of the current through the coil, and the magnitude and phase angle of the voltage across the coil. Also, calculate S, P and Q for the circuit
A three-phase, 60 Hz, six pole, wound rotor induction motor draws 10kw when driving its normal load. It draws 700 W when the load is diconnected. The rotor and stator copper losses under normal load are 295 W and 310 W respectively.
Consider two signals that have the same frequency. When the amplitude of the first signal is at its maximum, the amplitude of the second signal is at half its maximum from the zero level. What is the phase shift between the two signals
