A type of transformer known as an autotransformer is shown in Figure.
a. Assuming that all of the flux links all of the turns, determine the relationship between v1, v2, and the number of turns.
b. Assuming that the total mmf required to establish the flux is zero,find the relationship between the currents i1 and i2.
The addition of aluminum fins has been suggested to increase the rate of heat dissipation from one side of an electronic device 1 m wide and 1 m tall. The fins are to be rectangular in cross section, 2.5 cm long and 0.25 cm thick.
Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
The sampled signal is passed through an ideal LPF which rejects all frequencies above 8 kHz and has a gain Ts. Les sR(t) be the output of the LPF. Sketch LT[sR(t)], in which FT[] denotes the Fourier Transform, in frequency domain.
derive the BER (Bit Error Rate) of a 8-PAM (Pulse Amplitude Modulation) system in an AWGN (Additive White Gaussian Noise) channel.
Air is to be compressed from atmospheric pressure at 60oF to 100 psia in a centrfugal compressor (isentropic efficiency about 0.7). The flow rate will be 500 lbm/min. Specify the horsepower required for the driving motor
The gain of the antennas must be increased when the TDMA system described in part (d) is used because the bit rate is higher than with FDMA and the noise power in the receiver is therefore higher
Draw all force vectors on charge 2 due to every other charge. Label each vector accordingly with two subscripts. Draw the vectors so that the tail of each vector originates on the charge.
a) if x(t) is even, show that its Fourier transform is real for all w (i.e: its imaginary part is identically 0) b)if x(t) is odd, show that its Fourier transform is imaginary for all w (i.e: its real part is identically 0)
paper clips can be attracted by making a nail connected to the battery using the principle of electromagnetism but how can we make a car or moving paper clips using the same principle of electromagnetism.
Design a 4 input, 1 output combinational circuit. the input represents a 4-bit number, N = X3X2X1X0, which ranges from 0 to 15. The output, PN is 1 when N represents a Prime Number, otherwise PN is 0.
A sample of vinegar is 4.8% acetic acid, HC2H3O2, by weight, andhas a density of 1.00g/mL. Calculate (a) the grams of acetic acidin 1 liter of vinegar (b) the molarity of acetic acid invinegar. calculate the concentration of an ..
A school has 100 lockers and 100 students. All lockers are closed on the first day of school. As the students enter, the first student, denoted by S1, opens every locker. Then the second student, S2, begins, with the second locker denoted L2, and ..
