A parallel resonant circuit with quality factor 120 has a resonant frequency of 6 × 106 rad/s. Calculate the bandwidth and half-power frequencies.
a) What are the FIVE requirements for synchronizing the alternator tot he grid b) What should happen once the synchronous alternator is synchronized At that very instant, what should happen if the above five conditions are met
Market research and a competitive analysis are typically used in order to determine the feasibility of a new technology. How you could use advanced market research in order to remain competitive
A filter with a great deal of attenuation must be placed in an amplifier chain. Ignoring all considerations other than the desire to minimize noise figure, would it be preferable to put the filter before or after a low noise amplifier Why
Discuss briefly the implications of these values of T1 for ultrasonic imaging. Repeat the calculations above with the angle of incidence of the ultrasound beam now being 60 degrees.
A coaxial cable contains material with a dielectric constant of 9. The diameter of the inner conductor is 2 mm and the diameter of the outer conductor is 12 mm. Determine the characteristic impedance in ohms
A wire with a circular cross section of radius a = 10[mm] carries a current of 10 [A]. Assuming thecurrent is uniformly distributed in the cross section, determine the volume current density.
Explain the following terms; (i) critical radius of insulation. (ii) economic lagging thickness.
Transmission line A coaxial transmission line has characteristic impedance Z0 = 50 ohms and has length L = 200 m and phase velocity vp = 2.0e8 m/s. The end at x = 0 is terminated with Rs = 50 ohms and the end at x = L is terminated with RL = 75 oh..
Suppose an engineer is designing an external PCB board with an abnormally large number of programmable devices and is unsure of which protocol to choose for his hardware (DAC s, ADCs,PGAs, and Digital POTS/Trimmers)
In a swamped common-emitter BJT amplifier, as shown below, if Vcc = 12 V, R1 = 8.2 k , R2 = 10 k , Rc = 500 , RE = 1 k , VBE = 0.7 V, and = 100, what is the transistor's emitter current
Outage occurs when the users are located such that the out-of-cell interference is too large. For a given outage probability pout, give an approximate expression for the spectral efficiency of the system as a function of K, a and /3.
