An integral controller is used for speed control with a setpoint of 12 rpm within a range of 10 to 15 rpm. The controlleroutput is 22% initially. The constant KI = -0.15% controller output per second per percentage error. If the speed jumps to 13.5 rpm, calculate the controller output after 2 s for aconstant error.
calculate the amout of mmf generated by a coil of wire having 1300 turns and carrying milliamperes of current?
A dc motor takes an armature current of 105 A at 480 V when running at 720 rpm . The resistance of the armature circuits is 0.2 Ω and the field resistance is 96 Ω what is the torque developed in the armature
A sinusoidal signal x(t)=cos(100πt) is sampled at 80Hz and then reconstructed using a perfect lowpass filter with bandwidth 40 Hz. what is the equation of reconstructed signal and its frequency.
A 4.8 mF capacitor has been charged to11 V. The energy storedin the capacitor is used to light up a 0.3 KOhm lamp. Find the current flowing through the lamp 2.1 sec after the switch was turned on.
Capture the following system behavior as an HLSM. The system counts the number of events on a single bit input B and always outputs that number unsigned on a 16-bit output C, which is initially0. An event is a change from 0 to 1 or from 1 to 0.
Assume that this whole system is linear, so that, if the pressure on a sprinkler is halved, the area covered (as well as the flow rate) will be halved. This is true until the pressure is reduced below 20psi, at which it does not work at all.
Design and implement a sequential circuit for even parity check using T flip-flops. A binary code is received bit by bit in serial. The circuit output is 0 when the number of 1s in binary code is even; otherwise, output is 1.
A switch is made with an n-channel MOS device in a technology for which oxide thickness is 20 nm, minimum channel length is 1 um, unCox = 100 uA/V2, and VTH = 0.8 V. The devices operates in deep triode (i.e. small VDS)
An electron is shot into one end of the solenoid. As it enters the uniform magnetic field within the solenoid, its speed is 800 m/s and its velocity vector makes an angle of 30 degrees with the central axes of the solenoid.
A signal, bandlimited to 1Khz, is sampled by multiplying it with a rectangular pulse train with repetition rate 4KHz and pulse width 50 μs. Can the original signal berecovered without distortion, and if so, how
you have a RC circuit with an unknown capacitor. You have a 20V source and a 33k ohm resistor. the question states. The voltage Vc for the network has risen to 16V 5seconds after the switch was closed. Determine the value of C in microfarads.
Sketch basic characteristics of an-channel J-FET (ID vs. VDS andID vs. VGS) and explain why it may be used asa constant current source and a voltage controlled resistor.Indicate the parts of the characteristics where these functions canbe realized..
