For a thevenin equivalent circuit consisting of a voltage source Vg and an impedance Zg = Rg + jXg, i. show that the circuit delivers maximum average power to a load Zl = Rl + jXl when Rl = Rg and Xl = - Xg ii. show that maximum average power transfer theorem for ac circuits.( in both cases Vg and Zg are fixed and the load is variable)
For input signal voltages between these limits, the input should pass unaltered to the output. The peak current drawn from the input source may not exceed 1mA. You may use any circuit component we've studied except opamps.
Consider an AlGaAs based heterostructure laser diode which has an optical cavity of length 200 microns. The peak radiation is at 870 nm and the refractive index of GaAs is about 3.7. What is the mode integer m of the peak radiation
(a) Determine the mean, variance, and standard deviation of X. (b) Determine the value for x such that P(-x
Two soccer players start from rest, 34 m apart. They run directly toward each other, both players accelerating. The first player's acceleration has a magnitude of 0.42 m/s2. The second player's acceleration has a magnitude of 0.41 m/s2.
a closed conical tank with diameter of 1.50 and height of 3.00 m, sitting on its circular base has 1.00m depth of water. Suppose the tank is upside down and is made to stand vertically that way using some device.
A current filament carrying I in the -az direction lies along the entire positive z. At the origin, it connects to a conducting sheet that forms in xy plane. a) Find k in the conducting sheet.
c) Write the SOP boolean equations as obtained directly from the partial truth table above and sketch a logic circuit diagram for them. d) Reduce the above equations step-by-step into the simplest form that would use only NAND gates.
For pulse oximeter signals for heart rates less than 240 beatsper minute, what do you expect will be the important spectral andother signal characteristics that need to be preserved in an electronic system.
A 3-phase, 60 Hz supply and two 3-phase synchronous machines are available. Determine the speed, and a suitable number of poles, for each synchronous machine to provide: a) A 3-phase, 180 Hz supply. b) A 3-phase, 500 Hz supply.
A peri-stimulus time histogram (PSTH) is a commonly usedformat for displaying neurophysiological data. In a PSTH, theaverage firing rate of a neuron is depicted as a function of time.Trials are aligned in time onto the occurrence of a stimulus orb..
