The self inductances of two magnetically coupled coils are 288mHand 162mH. The 288mH coil has 1000 turns and the coefficientbetween the coils is 1/3. The coupling medium isnonmagnetic. When coil 1 is excited when coil 2 open, theflux linking only coil 1 is 0.5 as large as the flux linking coil2.a. how many turns does coil 2 have?b. what is the value of P2 in nanowebers/amp?c. what is the value of P11 in nanowebers/amp?d. what is the ratio(φ22/φ12)?
Write a brief explanation of the principles of the super-heterodyne receiver. It may help to use a simple block diagram to express the process. Explain the purpose of the Intermediate Frequency amplifiers,
Shannon's Law describes the relationship between bandwidth, signal power, and noise in determining the theoretical maximum Capacity in bits per second of a particular communications channel.
(a) Determine a unit vector in the direction of Q at P(1, 2, 1) (b) Find the component of Q at P in the direction of PT where T is point (5, 3, -4) (c) Where is Q the same as the unit vector of \(a_{x}+11a_{y}+10a_{z}\)
An input signal of 10V at 0o and a frequency of 1592 Hz is applied to a parallel RC circuit with resistor R = 100 ohm and capacitor C = 1 F. what is The source current.
What is the bandwidth required so that the modulated signal contains atheist 90% of the power of the unmodulated carrier. A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.
Determine whether the discrete signals below are periodic. If the signal is periodic, determine the number of samples per period. (a) x[n]=cos(πn) (b) x[n]= -3sin(.01πn) (c) x[n]= 1+cos((πn)/2)
