The bandwith of a series resonant circuit is 400 Hzif the resonant frequency is 4000 Hz, find Q. and if R = 10 ohms, what is the value of XL at resonance", and Find the inductance L, and capacitance C of the circuit
Two delta-connvected loads are connected in parallel and powered by a balanced Y-connected system. The small of the two loads draws 10k VA at a lagging Power Factor (PF) of 0.75, and the larger draws 25k VA at a leading PF of 0.80.
design a regulated poewr supply with these specs Output a dc voltage of 10 V Load Variation: 0.3 -10000ohms Ripple Factor: less 0.1% for 2000ohms load
Devise a detailed algorithm for a ring with p nodes so that each node would atttain the final sum of original node values. Determine the worst case communication steps for the algorithm.
A receiver has a sensitivity of 0.3 µV. The same receiver can handle a signal level of 75 mV without overloading. The receiver has a blocking dynamic range of 80 dB. If the desired signal has a level of 10 µV
A recent study has been carried out concerning radio propagation in railway tunnels. In this study, two railway tunnels of rectangular cross section are considered. Tunnel 1 has transverse dimensions of width a = 8 m
A three-point symmetric moving average filter, referred to as a weighted moving average is of the form \(y[n]=b(ax[nu22121]+x[n]+ax[n+1])\) (a) Determine as a function of a and b the frequency response \(H(e^{j\omega})\) of this system.
Electrons are liberated with zero velocity from the negative plate of a parallel plate capacitor, to which is applied a magnetic flux density B parallel to the plates. Prove that these electrons will not reach the positive plate.
e^-x=(1/e^x)=1/(1+x+(x^2/2)+(x^3/3!)+...) and compare with the true value of 6.737947*10^-3. Use 20 terms to evaluate each series and compute true and approximate relative errors as terms are added.
a) Find the current out of the current source. b) Find the current through the 200-ohm resistor. c) Calculate the power delivered by the source.
Suppose a data array has 30 numbers sorted from low to high already, where no two numbers are equal. We need to search whether any of the two randomly given key numbers, key1 and key2 is in the array. If yes, then find out the position index(es) f..
In the difference equation below K is a real number greater than 0. y[n) = x[n] + Ky[n] A) (2pt)Find the range of values of K that makes the impulse response grow without bound. B)
For a symmetric dielectric slab waveguide with the following parameters: n2 (core)=1.7, n1 (cladding) = 1.6 Calculate the range of core thickness such that the waveguide supports TE0/TM0 and TE1/TM1 modes but not TE2 modes.
