Consider the financial aspects of the digital thermometer project. The project cost is estimated at $10,000. The total manufacturing cost of the digital thermometer, as called for in the specifications, total $150(that is, $95 parts plus $40 labor plus $15 overhead). In order to sell each digital thermometer, consider an additional cost of $50 to cover the company's administrative overhead and selling expenses. The net selling price of each digital thermometer will be $250. Determine the following using general problem solving skills without considering the changing value of money due to inflation: a. What is the net profit for each digital thermometer sold? b. If the net profit is used to pay off the project development costs, how many digital thermometers will have to be sold to recover the $10,000 investment? c. At the projected annual volume of 1000 units per year for the product, roughly how long will it take until the $10,000 is recovered? "This is the break-even point for the company.
Analysis of discrete time waveforms in z domain, A discrete time domain signal x(n) - u(n) - u(n-10) is decomposed and plotted. It is then examined in the z domian by appropriate transformation and algebraic manipulation.
our senior design team is designing a force sensor to measure a force signal and analyze the signal with a microcomputer (binary system). The analog force signal is between 10 N and 70 N and has the frequency bandwidth of DC - 1000 Hz.
"Power Outage" refers to that the receive signal power falls below a certain threshold. Consider for a RF signal in a Rayleigh fading channel with average receive signal power 22 = - 80dBm. What will be the power outage probability of this channel..
Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV. If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifi..
Watts in Cassette Players, A walker's cassette tape player uses 4 AA batteries in series to provide 6V to the player circuit. The four alkaline battery cells store a total of 200 watts-second of energy.
BJT Circuit Configurations Compare the input and output impedance for each configuration. Compare the voltage gain and current gain for each configuration.
A load impedance ZL = 100 + j80 is to be matched to a 75 ohm line using a single shunt-stub tuner. Find two designs using open-circuited stubs. Include both smith chart and analytical analysis.
Determine zero-input response of (D2+4D+40)y(t)=(D+2)x(t) with initial condition y0(0)=2 & dy0(0)/dt=16.78.
Determine the settings Z1, Z2 & Z3 for the relay at B12.
Calculate the value of vL developed across a 300 H coil when the instantaneous rate of change in component current equals 500 mA/s.
50 kg of a certain gas is contained within a piston-cylinder assembly. the gas undergoes a processwhich the pressure volume relationship is PV = constant. (n=1.5) the given conditions as follows : p1= 6 bars, v1=0.2 cubic meters ,and v2= 0.4 cubic..
