consider the following drequency response os a system
Hw(w) = 20(jw + 10)^2/ jw(jw +100)
a) Find and plot the straight-line approximations to the amplitude and phase response bode plotsb) sketch the approximate amplitude-response bode plot od this system using the straight-line approximation and approximate amplitude values at the break and/or peak frequencies.c) sketch the approximate phase-response bode plot od this system using the straight-line approximation and a few calculated points
The following test data were obtained from testing a 48kVA, 4800/240-V, step down transformer: Open-circuit test Voltage (V) 240 Current (A) 2 Power (W) 120 Short-circuit test Voltage (V) 150 Current (A)10 Current
Assume a buck converter contains a synchronous rectifier. Does it operate in the discontinous conduction mode at light load Why What does the inductor current waveform look like
A circuit consists of a current source, i=0.030 sin 500t, in parallel with L=20mH, C=50 micro Farads and R=25 Ohms. a. Determine the voltage V across the circuit. b. Solve for the power factor of the circuit.
For a circuit we would like to implement, there are two control signals: x and y. If xy = 01, an 8-bit value R is incremented by 1 and control goes to a second state. If xy = 10, R is cleared to zero and control goes from the initial state to a th..
A 2000kW synchronous motor operates at a three - phase line-to-line voltage of 4kV. It has a synchronous reactance of 4 ohms per phase. Calculate a) The nominal full load current of the machine when the excitation voltage E0 ( line - to-line) is 4k..
Determine the net chage delta Q that flowed through a resistor over teh specified time interval for each of the following currents: (a) i(t) = 0.36A, from t=0 to t=3s (b) i(t) = [40t +8] mA, from t=1s to t=12s
for the circuit where Vr=30 Ohms, L=20 mH, C=39uF, and e=squareroot of 2(20)sin(1000t+40 degrees) a. Determine I, Vr, and Vc in phasor form b. Calculate the total power factor and indicate whether it is leading or lagging
You need to upgrade your crystallizer. Your company bought a new 1000 ft2 crystallizer 5 years ago for $450,000. You believe that your company has expanded sufficiently to need a 5000 ft2 crystallizer. What is the price in today's dollars
a) the synchronous generator has a unique ability whihc places it at the top of the heap of all machines that might be used for generation of electric power. This unique capability is what allows the business of electric dispatch to even occur.
Determine the Voltage across the electrical model of a cell membrane in a nerve cell
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
