Given the recent emphasis on solar energy, solar radiation has been carefully monitored at various sites in Florida. For typical July days in Tampa, 30% have total radiation of at most 5 calories, 60% have total radiation of at most 6 calories, and 100% have total radiation of at most 8 calories. A solar collector for a hot water system is to be run for six days. Find the probability that three of the days produce no more than 5 calories, one of the days produces between 5 and 6 calories, and two of the days produce between 6 and 8 calories. What assumptions are you making in order for your answer to be correct?
A process has the dynamics G(s)=5/s^2. Design a unity negative feedback controller of the form G.c(s)=Ks+1 for a step response exhibiting approximately 15% overshoot.
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
Explain why it is important that the stimulus waveforms signals in a test waveform bench be synchronized to the inactive edge ofthe clock of the sequential circuit to be tested.
An amplifier with a voltage gain of +40 dB, an input resistance of 10 kO, and an output resistance of 1 kO is used to drive a 1-kO load. What is the value of Avo Find the value of power gain in dB
A DC notor is to be driven with a 20 kHz signal. Using the HCS12 PWM function, develop the c code to drive the motor at approximately 60% of its full drive level. The e clock is 24 MHz. Use channel 0.
a) Make a table showing each load and its complex power. b) Determine the total complex power and the overall power factor. c) Determine the magnitude of the total current supplied by the 600V source.
The onboard antenna has EIRP=60dB. Estimate aproximate area of effective aperture of the consumer receiving ground dish antenna without taking into account additional losses such as polarization loss, atmospheric absorptions.
A continuous-time signal x(t)=cos(2πt) is sampled every T seconds, resulting in a discrete-time signal x[n] = x(nT) . Determine whether the sampled signal is periodic and if the signal is periodic, determine the number of samples in the fundamenta..
Write two equations for the mesh currents shown in standard form. find the values of i1 and i2 find the voltage V (over the 2 Ohms resistor) and the current i (over the 3 Ohms resistor)
design and wire a circuit that uses a dpdt relayto apply opposite polarity voltages to the rotor of a small dcmotor upon the throwing of a spst "direction" switch. there should also be a separate on/off switch in order to stop the motor before cha..
