The ripple on the control voltage creates sidebands around the carrier at the output of a PLL, equivalently disturbing the phase of the VCO.
Explain why the PLL suppresses the VCO phase noise (within the loop bandwidth) but not the sidebands due to the ripple.
Draw an inverting amplifier using an op amp with component values. Now, tell me where the virtual ground is. What are the properties of a virtual ground? What is the closed-loop voltage gain, input impedance, and bandwidth?
A votage pulse of amplitutde 10V begins at 5-sec and lasts for 20 msec,which is short compared with the respponse times and time constants of the system.This impulse si then passed through and integrator.
A machine produces photo detectors in pairs. Tests show that the first photo detector is acceptable with probability 3/5. When the first photo detector is acceptable, the second photo detector is acceptable with probability 4/5.
A reactor is fueled with 4 kg uranium enriched to 20 atom-percent in 235 U. The remainder of the fuel is 238 U. The fuel has a mass density of 19.2 g/cm3. What is the mass of 235U in the reactor?
The machine is to be operated as a motor, with a terminal voltage of 400 V (phase voltage). The armature current is 50 A, with power factor 0.85, leading. Determine Eb, field current, torque developed, and power angle δ.
Flux weakening causes problems in both generators and motors. In generators, the effect of flux weakening is simply to reduce the voltage supplied by the generator for any given load. In motors, the effect can be more serious.
the output response for a system is given as vot a1 - e-at sinat. is this a proper representation for an output
a series-tuned resonant circuit operates at a resonant frequency of 1 mhz and contains a 0.1 microfarad capacitor and
A 20-V-rms 60 Hz ac source isin series with an ideal diode and a 100 ohm resistance. Determine the peak current and peak inverse voltage(PIV) for the diode.
Find an expression for the rms (root-mean-square) speed of these particles, assuming them to be spheres of diameter and density
A 3-phase, 440VAC, 6-pole, 60Hz, wye connected induction motor takes 30KVA at .8 power factor lagging, and runs at a slip of 3.5% at full load. The stator copper losses are 500W, and the rotational losses are 350W.
Write the Boolean expression and draw the gate logic diagram and typical PLC ladder logic diagram for a control system wherein a fan is to run only when all of the conditions are met -Input A is OFF -Input B is ON or input C is ON, or both B and C ..
