The block diagram of a motor-control system with tachometer feedback is shown in Fig. 2P-46. Find lhe range of the tachometer constant K, so lhal the system is asymptotically stable.
Draw the circuit diagram of FWR with inductor filter and explain its operation.
The NF (dB) is defined as 10log(SNRin/SNRout) - in the unit of dB. If we are given the values of SNRin and SNRout in dB unit, how do we calculate NF (dB) in terms of dB, and how do we calculate NF in term of a pure ratio
What is resistors and Types of Resistors ? and What is the main Difference between Potentiometer and Rheostats? Full report required to accepte the answer !
A commutator motor with its armature supplied from variable voltage source. As the voltage is varied from 0 to 600V,the drive speed varies from 0 to 1600rpm, the field flux isconstant, all losses-ignored.
A wound-rotor induction motor is operating at rated voltage and frequency with its slip rings shorted and with a load of about 25 percent of the rated value for the machine.
At standard sea-level conditions, if the flow velocity at some region of the flow field exceeds about 250 mi/h, compressibility begins to have an effect in that region. Calculate the velocity of the flow in the test section of the wind tunnel abov..
Group and phase velocity in uniaxial crystals: a. Derive an expression for the group velocity of the extraordinary wave in a uniaxial crystal as a function of the polar angle of the propagation vector.
Calculate the transfer function and calculate the resonance frequency, fo of the circuit shown in calculate the cut-off frequencies fit and II of the circuit.
A coaxial line 5.6m long has distributed parameters R=6.5ohm/m, L=3.4 uH/m, G=8.4 mS/m, and C=21.5 pF/m. If the line operates at 2MHz, calculate the characteristic impedance and the end-to-end propagation time delay.
The left and right channels of a analog stereo signal are sampled at a 45kHz with each signal being converted into a digital bit stream using a 12-bit A/D converter. Determine the combine bit rate of the two channels after sampling.
