It is required to design an amplifier to have a nominal closed-loop gain of 10 using a battery operated amplifier whose gain reduces to half its normal full-battery value over the life of the battery.
If only 2% drop in closed loop gain is desired, what nominal open-loop amplifier gain must be used in the design? (The change in A is large, it is inaccurate to use differentials)
What value of B should be chosen? If component value variation in the B network may produce as much as ±1% variation in B, to what value must A be raised to ensure the required minimum gain?
What are the fundamental dimensions of s? What is the diameter of the hailstone in units of inches? What is the volume of the hailstone in units of liters?
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
(1) a lighting load drawing 10kW, (2) an induction motor drawing 10 kVA at 0.9 power factor lagging, and (3) a synchronous motor operating at 10 hp, 85% efficiency and 0.95 power factor leading (1 hp = 0.746 kW). Determine the real, reactive, and ..
Determine the FWHM diameter of the beam 50 mm from the second lens (ie. 100 mm from the first lens.) A third lens is placed at the point with a focal length off.
(a) At t = 0, the current flowing in a 0.5-H inductance is 4 A. What constant voltage must be applied to reduce the current to 0 at t = 0.2 s (b) Starting at t = 0, a constant 12-V voltage source is applied to a 2-H inductor.
Production cost refers to prime cost plus 1. factory, administration and sales overheads 2. factory overheads
What is the inverse Laplace transform of 32/s(s^2+64). Please show all work.
A rectangular loop of wire in free space joints point A(1,01,) to point B(3,0,1) to point C(3,0,4) to point D(1,0,4) to point A. The wire carries a current of 6mA, flowing the az direction from B to C. A filamentary curent of 15A flows
The voltage and current at the terminals of the circuit element are zero for t 0 they are v = 90-90e^(-1000t) V i = 50e^(-1000t) mA A) Find the maximum value of the power delivered to the circuit B)
The circuit elements have parameter values L1= 1H, L2=1H, C = 1F, and R = 2.5+(0.5x0.244) ohms. The resistor value is then between 2.5 and 2.9995 ohms. Using Kirchhoff's voltage and currents laws, derive the 3thorder differential equation for vo(t)..
A stream that contains 50% by mole cyclohexane in nitrogen is fed to a reactor that operates a constant pressure and temperature. The reactor pressure is 5 bar and the desired conversion of cyclohexane is 85%. Determine the amount of heat per mol ..
