A 450 piece/hr 10 hr B 500 piece/hr 8 hr A set of unsharpen ed tools costs $1,500 and can be ground 15 times. The cost of each grinding is $20. The time required to change and reset the tools is 2 hours, and such changes are made by a tool-setter who is paid $16/hour. The production machine operator is paid $15/hour, including the time that the machine is down for tool sharpening. Variable overhead on the machine is charged at the rate of $30/hour, including tool-changing time. At what speed should the machine be operated to minimize the total cost per piece?
Problem Feeder - Transformer, A single-phase load is supplied through a 35 kV feeder whose impedance is 115 + j380 Ohms and a 35 kV, 2400 V transformer whose equivalent impedance is 0.26 + j1.21 Ohms referred to its low voltage side.
Generate a sine wave signal with amplitude A=1, and frequency=0.1592Hz. Using a uniform PCM method, quantize it ot a) 8-level and b) 16-level. Plot the original signal and the quantized signals on the same axes
the frequency response h(e^jw) of a length-4 finite impulse response filter with a real impulse response h[n] that the following specific value: h(e^j0)=13, H(e^j3pi/2)=-3-j4, and h(e^jpi)=-3. determine the 4th discrete fourier transform (DFT) of ..
The energy (power) in Watts in an electrical circuit is described by P = VI, where V is volts and I is current
Discuss different applications that could use non-inverting and inverting amplifier circuits. Will the actual op amp characteristics cause any challenges if used for each application What effect will high source resistance have on your output volta..
draw out a schematic that implements a 3-bit XOR gate, but consisting of only 2-bit NAND gates. Your schematic should have from 8-10 NAND gates, but NO other logic function such as OR, AND, INV gates can be in your final design.
The Russian president and the Chinese counterpart need to come to an agreement by telephone. Neither can speak and understand each other's language. They need to employ translators. Compare this layered communication to OSI layers.
