A generator with an output voltage of 2 mV has a generator output resistance of 75 Ω. It drives an amplifier with an input impedance of 200 Ω. The amplifi er gain is 30, the output impedance is 300 Ω, and the amplifier load is 600 Ω. What is the output voltage?
A DC machine has the following parameters: Ra =1Ω, La = 4 mH , kPWM = 100 . (a) Design the current loop with a bandwidth of 1000 rad/s and phase margin of 900. (b)Given a step current command, ia*(t) = 5u(t)A, calculate the actual current,i(t)
The field circuit has a dc voltage of 200 V, and the maximum IF is 10 A. The open-circuit characteristic of this motor is shown in Figure. Answer the following questions about the motor, assuming that it is being supplied by an infinite bu..
A teleoperated control system has an operator and a remote machine. The usual teleoperation system is based on a one-way link to the machine and limited feedback to the operator. However, the use of a two-way coupling will result in a better opera..
Derive the equations of motion of the system - Create a Simulink model using the differential equations
Desired D.C. Output : 10 V Load Variation: 0.3 kilo-ohms - 10 kilo-ohms Ripple Factor: Less than 0.1% for 2 kilo-ohms load Load Regulation: Better than 3 mV for a 1 mA change in load current
What happens to an ECG signal when a triggered average is applied I can see from the graphs that the peaks directly before and after the triggered peak become more and more blurry, but I don't understand
A ¼ watt resistor has a resistance of 3.2KW what is the maximum current that the resistor can handle. If the wattage rating is doubled, will the maximum current double.
A certain amplifier has an open-loop gain in the midrange of 180000 and an open loop critical frequency of 15000 Hz. If the attenuation of the feedback gain is .015, what is the closed-loop bandwidth. solve?
A pair of synchronous machines, on the same shaft, may be used to generate power at 60 Hz from the given source of power at 50 Hz. Determine the minimum number of poles that the individual machines
Why is the idea of using electronic cash still so popular despite the many failures in the last few years
What would be the DFT frequency-domain sample spacing in Hz if the N-sample X(n) time sequence was padded with 4N zero-valued samples and we performed a DPT on that extended-time sequence
Demonstrate that the peak critical heat flux occurs at approximately one-third the critical pressure (Pc = 221 bars). Since all common fluids have this characteristic, suggest what coordinates should be used to plot critical heat flux-pressure val..
