1. a cost to produce, P, of $4.00. If we were able to reduce this to $3.55 through greater attention in the design, and if the cost to improve the design (in NRE) is $35,000, how many units must we sell to recover the increased design cost? Calculate for both the = 50% and = 75% cases. What conclusions can you draw from this?
2. In the electronics business, mark-up is in the order of 100% to 130% at each level of middleman. Let's say that it is 100%. Let's further say that your product passes through three levels of middleman, that your product is produced in accordance with the example (all the same numbers), and that = 50%. What are your retained earnings as a percentage of the final retail price?
Determine the signal/noise ratio (Eb/No) in input of the receiver for each modulation format presented below if symbol error rate (SER) is required to be 10-^4 (use the coherent detection), for the solution the appropriate graphs can be used inste..
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Come up with (draw) a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
How many voice channels are carried by a E1 transmission given 8 kHz sampling and 8 bit words? Why is an end of frame marker always required in a digital telephony system?
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a non-inverting configuration with dual supplies (+5v and -5v)..
Efficiency in a power transformer is 98.6% when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
The resistance per 304.8 m of copper wire uses in the extension cord of AWG 14,12,10,8 and 6 are 2.58,1.62, 1.02, 0.64 and 0.41 respectively. Assume a 2% allowable voltage drop. Show all working .
Explain an engineering solution for the BP Oil Spill in the Gulf of Mexico. Discuss the impact of the above engineering solution in an environmental context. Do not discuss the environmental impact of the BP Oil Spill.
The contects of a six-bit register are initially 100101. The register is shifted four times to the right, with the serial input being 1101. What are the contents of the register after each shift
the solutions at both frequencies about a total transit time of 1000 years (speed of light in a vacuum result) such that subtracting one from the other leaves just the delay that is of order of 1 second.
Identify one emerging technology, and evaluate its future prospects by identifying the cultural and social factors that may prevent or promote its successful application. Use concrete details to support your answer.
A 60-Hz, single-phase transmission line has a length of 80 miles. Its shunt conductance (G) is 3.4×10?11 S/mile, resistance (R) is 0.1 ?/mile, capacitance (C) is 16 pF/mile, and inductance (L) is 0.56 mH/mile 220 kV, 220 MVA with power factor
